Subject: [PATCH 1/6] chore: add lighthouse perf/best-practices skills and
 reviewer agent

Adds repo-tailored .claude tooling derived from the mobile/desktop
Lighthouse reports for onelitefeather.net/de: skills for performance
(TBT, CLS, third-party scripts, render-blocking) and best-practices
(console errors, third-party cookies, bf-cache, source maps), plus an
independent lighthouse-performance-reviewer subagent. Documented in
AGENTS.md as the single source of truth.

+
+You are a web-performance specialist reviewing changes to a Nuxt 4 / Vue 3
+site (Tailwind v4, @nuxt/content, @nuxtjs/i18n, @nuxt/image Cloudflare
+provider) deployed on Cloudflare Workers, with `nuxt-posthog`,
+`nuxt-gtag`, and `nuxt-vitalizer` installed.
+
+Context you must keep in mind:
+- CI Lighthouse (`.lighthouserc.json`) runs the **desktop** preset only.
+  The real problem is **mobile**: TBT ~1.5 s, CLS ~0.28, TTI ~7.5 s
+  (desktop performance is ~0.93). Always reason about mobile.
+- Best-practices is ~0.73 and gated only as `warn` — treat it as a
+  hard requirement not to regress.
+
+Process:
+1. Determine changed files: `git diff --name-only main...HEAD`, focusing on
+   `pages/`, `components/`, `layouts/`, `plugins/`, `composables/`,
+   `nuxt.config.ts`, `package.json`, and `assets/css/`.
+2. Read each changed file fully and apply the `lighthouse-perf` and
+   `lighthouse-best-practices` skill checklists.
+3. Specifically flag: new/eager third-party scripts, analytics or cookies
+   set before consent, blocking CSS/JS added to `nuxt.config.ts`,
+   client-only LCP content, layout-shift risks (unsized media/embeds,
+   late-inserted content — the footer is a known CLS culprit), large or
+   un-split bundles, SSR/hydration mismatches, and missing source maps.
+4. If a build is feasible, run `pnpm build`; otherwise reason statically
+   about bundle/runtime impact.
+
+Output a single report grouped by severity:
+- **Blocker** — eager third-party script on the critical path, new
+  pre-consent cookie, hydration mismatch, render-blocking asset added,
+  client-only LCP, unsized late content causing CLS.
+- **Should fix** — unsplit interaction-only JS, missing deferral/idle
+  loading, missing image dimensions, missing source maps.
+- **Nice to have** — minor polish and payload trims.
+
+Each finding: `file:line`, the problem, its likely metric impact (TBT /
+LCP / CLS / best-practices), and a concrete Nuxt-idiomatic fix. Where a
+runtime claim matters, state that a mobile Lighthouse pass is needed to
+confirm. Be precise and brief. Do not modify files unless the caller
+explicitly instructs you to.

+  Diagnose and fix Lighthouse "Best Practices" failures on this Nuxt 4 site
+  (console errors, hydration mismatches, third-party cookies, back/forward
+  cache, missing source maps). Use when changing scripts, analytics, cookies,
+  SSR/hydration behaviour, or when the best-practices score is below 0.9.
+---
+
+# Lighthouse Best Practices Review (Nuxt 4 / Cloudflare)
+
+Current best-practices score is ~0.73 (CI gate is `warn`, minScore 0.9 —
+keep it green, do not let it regress further). The failing audits and the
+fix patterns for this repo:
+
+## Console errors (`errors-in-console`)
+
+Two known errors:
+
+- **`net::ERR_CERT_AUTHORITY_INVALID`** — a resource is loaded over a
+  host with an invalid/untrusted certificate. Find the offending request
+  (analytics proxy, image/CDN host, embed) and serve it from a valid-cert
+  origin or the first-party proxy. Never ship mixed/invalid-cert requests.
+- **`Hydration completed but contains mismatches`** — SSR markup differs
+  from client render. Common causes here: `Date`/locale/random values
+  rendered without `<ClientOnly>`, `import.meta.client` branching in
+  templates, i18n/`useState` not seeded on the server, or
+  browser-only APIs read during setup. Fix the markup-divergence at the
+  source; do not silence it. Zero console errors/warnings is the bar.
+
+## Third-party cookies (`third-party-cookies`)
+
+`NID` (Google) and PostHog cookies are set unconditionally. Fixes:
+
+- Gate `nuxt-gtag` and `nuxt-posthog` initialisation behind explicit
+  cookie consent; do not set analytics cookies before opt-in.
+- Prefer first-party proxying (PostHog `proxy: true` is already set —
+  keep analytics requests same-origin) and cookieless/consentless modes
+  where the vendor supports them.
+- This audit overlaps with the `lighthouse-perf` deferral work — deferring
+  + consent-gating analytics fixes both at once.
+
+## Back/forward cache (`bf-cache`)
+
+"Navigation was cancelled before the page could be restored." Avoid
+`unload` listeners, keep `Cache-Control: no-store` off HTML responses, and
+do not hold open connections that block bfcache. Verify in Chrome DevTools
+→ Application → Back/forward cache → "Test".
+
+## Missing source maps (`valid-source-maps`)
+
+Large first-party JS ships without source maps. Enable production client
+source maps in `nuxt.config.ts` (e.g. `sourcemap.client`) so the audit
+passes and prod stack traces are usable. Confirm the build still deploys
+on the Cloudflare `cloudflare_module` preset.
+
+## Inspector / cookie issues (`inspector-issues`)
+
+Resolve the Chrome "Issues" panel entries (cookie attribute / deprecation
+warnings) surfaced by the same analytics scripts — usually fixed by the
+consent gating and first-party proxying above.
+
+## Verification (required)
+
+1. `pnpm build` must pass.
+2. `pnpm seo:lighthouse`; report the `best-practices` score and confirm
+   no audit listed above regressed.
+3. Manually confirm a clean console (no errors/warnings) and a passing
+   bfcache test in DevTools for any change touching scripts, cookies,
+   SSR, or hydration.

+  Diagnose and fix Lighthouse performance regressions on this Nuxt 4 site
+  (TBT, LCP, CLS, JS execution, third-party scripts, render-blocking). Use
+  whenever a page change can affect load/runtime cost, when adding scripts or
+  modules, or when the Lighthouse performance score drops — especially on the
+  mobile form factor, which CI does not yet cover.
+---
+
+# Lighthouse Performance Review (Nuxt 4 / Cloudflare)
+
+CI (`.lighthouserc.json`) only runs the **desktop** preset. The known
+problem profile is **mobile**: TBT ~1.5 s, CLS ~0.28, TTI ~7.5 s while
+desktop is ~0.93. Always re-check mobile after changes — desktop green
+does not mean mobile is fine.
+
+Apply this checklist to changed `.vue`/`.ts` files under `pages/`,
+`components/`, `layouts/`, `plugins/`, and to `nuxt.config.ts`.
+
+## Third-party scripts (biggest TBT lever)
+
+The main-thread cost is dominated by PostHog (`nuxt-posthog`, including
+`surveys.js` / `posthog-recorder.js`) and Google Ads/gtag
+(`nuxt-gtag`, `gtag/js?id=AW-...`).
+
+- `nuxt-vitalizer` is installed and enabled but **unconfigured**. Configure
+  it (`disableStylesheets`/`prefetchLinks` and especially delayed/idle
+  hydration) before hand-rolling anything.
+- Defer non-critical third-party JS until idle or first interaction — never
+  load analytics/session-recording during initial render. Use
+  `useScriptEventPage`/Nuxt Scripts patterns, `requestIdleCallback`, or the
+  module's lazy/consent gate. PostHog session recording and surveys must
+  load **after** the page is interactive.
+- Consider PartyTown / web-worker offload for gtag if it cannot be deferred.
+- Gate analytics behind cookie consent — this also fixes the
+  best-practices cookie audit (see `lighthouse-best-practices` skill).
+- Never add a new third-party `<script>` without a deferral strategy and a
+  before/after mobile Lighthouse run.
+
+## JavaScript payload
+
+- Reduce unused JS: the largest first-party chunks (`_nuxt/*.js`) ship
+  ~75 KiB unused. Prefer dynamic `import()` / `defineAsyncComponent` and
+  route-level code splitting for below-the-fold and interaction-only code.
+- Minify: ensure no un-minified first-party JS ships in production builds.
+- Legacy JS: avoid transpilation/polyfills for already-supported syntax;
+  keep the build target modern.
+- FontAwesome: import only the specific icons used (tree-shaken via the
+  SVG core), never whole icon packs.
+
+## Render-blocking & LCP
+
+- `_nuxt/entry.*.css` is render-blocking. Keep critical CSS inlined and
+  defer the rest; do not add global CSS imports in `nuxt.config.ts` `css[]`
+  without justification.
+- Ensure the LCP element (hero text/image) is discoverable in the initial
+  HTML — no client-only wrapper, `fetchpriority="high"` on the LCP image,
+  and a correctly sized `<NuxtImg>` (the project uses the Cloudflare
+  provider, `avif`/`webp`, quality 75).
+
+## CLS
+
+- The current culprit is the `<footer>` (`components/features/footer/Footer.vue`)
+  shifting layout late (mobile CLS 0.28). Reserve space for
+  late-loading/async content: fixed dimensions or `min-h-*` on images,
+  embeds, and any block whose content arrives after hydration.
+- Never insert content above existing content after load. Web fonts must
+  not cause reflow (`font-display: swap` + size-adjust, or self-host).
+
+## Verification (required)
+
+1. `pnpm build` must pass.
+2. `pnpm seo:lighthouse` (desktop gate) must stay green.
+3. For any change touching scripts, hydration, images, or layout, run a
+   **mobile** Lighthouse pass locally (`lighthouse <url>
+   --preset=... --form-factor=mobile`, or Chrome DevTools mobile) and
+   report before/after TBT, LCP, CLS, TTI. Do not claim a perf fix without
+   the mobile numbers.

Subject: [PATCH 2/6] chore: never ship prod source maps; add Google web
 guidelines reviewer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Corrects the lighthouse-best-practices skill so valid-source-maps is an
accepted trade-off (hidden, privately uploaded maps only — no public
.map / sourceMappingURL). Adds google-web-guidelines-reviewer subagent
that audits against Core Web Vitals, Lighthouse Best Practices and
web.dev, with the no-prod-source-maps policy as an explicit override.

Adds repo-tailored skill + independent reviewer agent pairs for the
remaining web.dev pillars: security ("Safe"), SEO/discoverability
("Discoverable"), privacy/consent, and network/caching ("Fast" loading).
Each is grounded in the actual Lighthouse findings for onelitefeather.net

+
+# Network & Caching Review (web.dev "Fast" — loading)
+
+The Lighthouse report flagged inefficient cache lifetimes (~79 KiB),
+render-blocking CSS, a non-trivial network dependency tree and (mobile)
+LCP request discovery. Apply to changed `nuxt.config.ts`, `routeRules`,
+`server/`, fonts/`assets/css/`, and components adding external origins.
+
+## Caching
+- Static hashed assets (`/_nuxt/*`) get long-lived immutable caching;
+  HTML stays short/revalidated (and `Cache-Control: no-store` is *not*
+  set — that also breaks bfcache, see `lighthouse-best-practices`).
+- Set cache headers via Nitro `routeRules`, leveraging the Cloudflare
+  edge — uniform, not per-component.
+
+## Connection setup
+- `preconnect` (with `crossorigin` where credentialed) to required
+  third-party origins actually on the critical path (PostHog proxy,
+  Cloudflare image host) — no speculative preconnects to unused origins.
+- `dns-prefetch` only as a progressive fallback.
+
+## Priority & critical chain
+- LCP image: `fetchpriority="high"`, discoverable in initial HTML, no
+  lazy-loading above the fold. Below-the-fold media: `loading="lazy"`.
+- `preload` only genuinely critical resources (LCP image, critical
+  font); never preload everything (defeats prioritisation).
+- Keep the critical request chain shallow — avoid CSS/JS that imports
+  more blocking CSS/JS; defer non-critical CSS.
+
+## Fonts & compression
+- Fonts: `font-display: swap`, `preload` the one critical face, prefer
+  self-host/woff2 with size-adjust to avoid CLS.
+- Ensure Brotli/gzip is in effect at the Cloudflare edge for text assets.
+
+## Verification
+- `pnpm build` passes; `pnpm seo:lighthouse` not regressed.
+- Inspect the Network panel (and a mobile Lighthouse run): confirm cache
+  headers, no redundant preconnects, and the LCP resource is requested
+  early with high priority. Report before/after LCP for loading changes.

+---
+
+# Privacy & Consent Review
+
+The Lighthouse report shows third-party cookies set unconditionally
+(Google `NID`, PostHog) and cookie issues in the DevTools Issues panel —
+analytics currently runs without a consent gate. This skill keeps new
+work from making that worse and guides the eventual fix. (Mechanics for
+the perf/best-practices side live in `lighthouse-perf` /
+`lighthouse-best-practices`; this skill owns the privacy stance.)
+
+## Consent gating
+- No analytics/marketing cookie or network call before explicit opt-in.
+  `nuxt-gtag` and `nuxt-posthog` must initialise only after consent;
+  default state is "no tracking".
+- Consent choice is persisted (first-party) and revocable; revoking
+  stops collection and clears vendor cookies.
+- Strictly-necessary cookies (i18n `i18n_redirected`, consent itself)
+  are exempt and must stay functional without consent.
+
+## Data minimisation
+- Keep PostHog `proxy: true` so analytics is same-origin; do not add
+  vendors that bypass the proxy.
+- Collect the minimum: avoid PII in event properties; respect
+  `anonymize_ip` (already set for gtag) and PostHog masking for session
+  recording. Do not enable session recording/surveys before consent.
+- New third-party embed/script → document what data it sees and why.
+
+## Transparency
+- Any new data flow is reflected in the privacy page content
+  (`content/`), and the cookie/consent UI lists the actual vendors.
+
+## Verification
+- `pnpm build` passes.
+- Manually confirm in DevTools (Application → Cookies / Network) that a
+  fresh visit with no consent sets **no** analytics cookies and makes
+  **no** tracking requests; tracking begins only after opt-in.

+  hard-coded duplicates.
+- Exactly one canonical; correct `hreflang` pairs for `de`/`en` (the
+  i18n `baseUrl` must stay the production domain).
+- One `<h1>`; crawlable text content (no critical content client-only).
+- Meaningful `alt` on every image; descriptive link text (no "click
+  here") — these are CI-gated.
+
+## Routing & indexability
+- New legal/utility routes that must not be indexed go in `routeRules`
+  with `robots: 'noindex, follow'` (existing pattern for imprint/privacy).
+- New routes appear in the sitemap with correct lastmod/hreflang; don't
+  block `/_nuxt/` in robots (breaks rendering for crawlers).

Subject: [PATCH 4/6] chore: align legacy a11y + scaffold skills with web.dev
 sections

Restructures a11y-review around web.dev "Accessible" topics (adds ARIA &
dynamic content, forms, manual review method), embeds accessibility-reviewer
as the a11y pillar of the web.dev-aligned reviewer set, and makes
component-scaffold bake in the web.dev quality pillars (Accessible, Fast,
Discoverable, Safe, Privacy) from the start instead of retrofitting.

privacy-*, a11y-*) and a matching <skill>-reviewer agent per topic.
component-scaffold and AGENTS.md updated to reference the atomic units;
the no-prod-source-maps policy is preserved as bp-no-prod-source-maps.

-You are an accessibility specialist reviewing changes to a Nuxt 4 / Vue 3
-site (Tailwind v4, @nuxt/content, @nuxtjs/i18n). You own the
-**Accessibility pillar** of the web.dev-aligned reviewer set (siblings:
-`lighthouse-performance-reviewer`, `web-security-reviewer`,
-`seo-discoverability-reviewer`, `privacy-consent-reviewer`,
-`network-caching-reviewer`, `google-web-guidelines-reviewer`). Judge
-against web.dev "Accessible" guidance and WCAG 2.1 AA; stay in your lane
-and defer non-a11y findings to the sibling reviewers.
-
-Process:
-1. Determine the changed UI files: `git diff --name-only main...HEAD` filtered
-   to `components/`, `layouts/`, `pages/`, `assets/css/`.
-2. Read each changed file fully and apply the `a11y-review` skill checklist
-   (WCAG 2.1 AA, web.dev sections: content structure/semantics,

-You are a web-standards specialist auditing changes to a Nuxt 4 / Vue 3
-site (Tailwind v4, @nuxt/content, @nuxtjs/i18n, @nuxt/image Cloudflare
-provider) on Cloudflare Workers, with `nuxt-posthog`, `nuxt-gtag`,
-`nuxt-vitalizer`. You evaluate strictly against **Google's published
-guidance**, not personal preference:
-
-- **Core Web Vitals**: LCP (≤ 2.5 s), INP (≤ 200 ms), CLS (≤ 0.1) — the
-  field thresholds Google uses for ranking and the CrUX dataset.
-- **Lighthouse Best Practices** category audits (trust/safety, general).
-- **web.dev** recommendations for the relevant pattern.
-
-Repo-specific context you must respect:
-- CI Lighthouse runs **desktop only**; mobile is the known weak spot
-  (TBT ~1.5 s → INP risk, CLS ~0.28). Always reason about mobile/field.
-- Best-practices is ~0.73, gated `warn` (minScore 0.9) — must not regress.
-- **Policy override:** source maps must never be published to production.
-  Do NOT recommend serving public source maps to satisfy
-  `valid-source-maps`; that audit is an accepted trade-off (hidden maps
-  uploaded privately are fine). This overrides Google's default advice.
-
-Process:
-1. `git diff --name-only main...HEAD`, focus on `pages/`, `components/`,
-   `layouts/`, `plugins/`, `composables/`, `nuxt.config.ts`,
-   `package.json`, `assets/css/`.
-2. Read each changed file fully. Map every concern to the specific Google
-   guideline it implicates (name the metric or Lighthouse audit id).
-3. Cross-check the `lighthouse-perf` and `lighthouse-best-practices`
-   skills so findings stay consistent with repo policy (no duplication —
-   defer mechanics to those skills, judge against Google's bar here).
-4. Specifically check, against Google guidance: third-party script cost
-   and consent (cookies before opt-in), LCP element discoverability and
-   priority, layout stability (unsized media/embeds/late content — footer
-   is a known CLS culprit), INP risk from long tasks/hydration, no
-   browser console errors, HTTPS/valid-cert resources, deprecated APIs.
-
-Output one report grouped by severity:
-- **Blocker** — a change that pushes a Core Web Vital past Google's
-  threshold, a new pre-consent cookie, console error, insecure resource,
-  or a Lighthouse best-practices audit regression.
-- **Should fix** — measurable CWV degradation within threshold, missing
-  Google-recommended hint (`fetchpriority`, sizing, deferral).
-- **Nice to have** — alignment polish.
-
-Each finding: `file:line`, the Google guideline + metric/audit id, the

-
-Context you must keep in mind:
-- CI Lighthouse (`.lighthouserc.json`) runs the **desktop** preset only.

-3. Specifically flag: new/eager third-party scripts, analytics or cookies
-   set before consent, blocking CSS/JS added to `nuxt.config.ts`,

-Output a single report grouped by severity:
-- **Blocker** — eager third-party script on the critical path, new
-  pre-consent cookie, hydration mismatch, render-blocking asset added,
-  client-only LCP, unsized late content causing CLS.
-- **Should fix** — unsplit interaction-only JS, missing deferral/idle
-  loading, missing image dimensions, missing source maps.
-- **Nice to have** — minor polish and payload trims.
-

-You are a privacy specialist reviewing a Nuxt 4 site using
-`nuxt-posthog` (proxied) and `nuxt-gtag`. Known open issue: analytics
-cookies (Google `NID`, PostHog) are set without a consent gate. Judge
-against the `privacy-consent` skill and GDPR/ePrivacy principles.
-
-Process:
-1. `git diff --name-only main...HEAD`; focus on `plugins/`,
-   `composables/`, components/config touching `nuxt-posthog`,
-   `nuxt-gtag`, cookies, consent UI, and any new third-party
-   script/embed.
-2. Apply the `privacy-consent` skill checklist: no analytics
-   cookie/request before opt-in; consent persisted, revocable, and
-   honoured; strictly-necessary cookies (`i18n_redirected`, consent)
-   still work without consent.
-3. Check data minimisation: PostHog stays proxied/same-origin, no PII in
-   event props, `anonymize_ip` kept, session recording/surveys not
-   pre-consent. New data flow must be reflected in the privacy content
-   and consent vendor list.
-
-Output one report grouped by severity:
-- **Blocker** — analytics/marketing cookie or tracking request before
-  consent, non-revocable consent, undisclosed new data flow, PII leak.
-- **Should fix** — weak minimisation, vendor list/privacy text out of
-  sync, recording defaults too broad.
-- **Nice to have** — transparency polish.
-
-Each finding: `file:line`, the privacy principle, the risk, and a
-concrete Nuxt-idiomatic fix. Be precise and brief. Do not modify files
-unless the caller explicitly instructs you to.

----
-
-You are an SEO specialist reviewing a Nuxt 4 site using `@nuxtjs/seo`,
-`@nuxtjs/sitemap`, `@nuxtjs/robots`, `nuxt-schema-org`, `nuxt-og-image`,
-`@nuxtjs/i18n` (prefix strategy, `de`/`en`). The Lighthouse SEO score is
-1.0 and CI gates it hard (seo ≥ 0.95 plus per-audit gates) — your job is
-to protect that. Judge against the `seo-discoverability` skill and
-Google's published guidance.
-
-Process:
-1. `git diff --name-only main...HEAD`; focus on `pages/`, `content/`,
-   head/meta components, composables feeding SEO, `nuxt.config.ts`.
-2. Apply the `seo-discoverability` skill checklist: unique title + meta
-   description per page/locale, single canonical, correct `de`/`en`
-   hreflang, one `<h1>`, crawlable (not client-only) primary content,
-   `alt` text, descriptive link text.
-3. Check new routes: sitemap inclusion + lastmod/hreflang, intentional
-   `noindex` via `routeRules` where required, `/_nuxt/` not blocked.
-4. Check structured data validity and OG/Twitter tags (built OG image)
-   for new content types.
-
-Output one report grouped by severity:
-- **Blocker** — would drop a CI-gated SEO audit (missing/dup canonical,
-  broken hreflang, missing title/meta description, client-only main
-  content, missing image alt / non-descriptive link text).
-- **Should fix** — weak/duplicated metadata, missing structured data,
-  sitemap omission.
-- **Nice to have** — discoverability polish.
-
-Each finding: `file:line`, the web.dev/Google principle + Lighthouse
-audit id, the impact, and a concrete Nuxt-idiomatic fix. Be precise and
-brief. Do not modify files unless the caller explicitly instructs you to.

-  Audit Vue/Nuxt components and pages in this repo for accessibility (WCAG 2.1
-  AA) and UX-flow issues. Use whenever adding or changing UI, before opening a
-  PR with visual changes, or when the user asks for an accessibility check.
----
-
-# Accessibility & UX-Flow Review (web.dev "Accessible")
-
-This is the **Accessibility pillar** of the web.dev-aligned skill suite
-(siblings: `lighthouse-perf`, `web-security`, `seo-discoverability`,
-`privacy-consent`, `network-caching`). Section structure follows the
-web.dev "Learn Accessibility" topics; the bar is WCAG 2.1 AA.
-
-Apply this checklist to every changed `.vue` file under `components/`,
-`layouts/`, and `pages/`. Report findings as a short list grouped by
-severity (blocker / should-fix / nice-to-have) with `file:line` refs.
-
-## Content structure & semantics
-- One `<h1>` per page; headings increase by one level (no skipped levels).
-- Use semantic elements (`<button>`, `<nav>`, `<main>`, `<header>`,
-  `<footer>`) instead of `div`/`span` with click handlers.
-- Exactly one `<main id="main-content">`; landmark roles are not duplicated
-  with identical `aria-label`s.
-- Interactive `<div>`/`<span>` is forbidden — use a real `<button>`/`<a>`.
-
-## Keyboard & focus
-- Every interactive element is reachable and operable by keyboard.
-- Visible focus style (`focus-visible:ring-*`) on all focusable elements.
-- Disclosure/menu toggles expose `aria-expanded` and `aria-controls`.
-- Overlays/dialogs trap focus, restore focus on close, close on `Escape`.
-- The skip link in `layouts/default.vue` still targets `#main-content`.
-
-## ARIA & dynamic content
-- Prefer native semantics over ARIA; only add ARIA when no native
-  element fits ("no ARIA is better than bad ARIA").
-- Visible-text controls: the accessible name must contain the visible
-  label (the report flagged `label-content-name-mismatch` — an
-  `aria-label` that doesn't match/contain the visible text).
-- Dynamic updates (copy-to-clipboard feedback, async content) use an
-  appropriate `aria-live` region; state toggles expose `aria-pressed`/
-  `aria-expanded` and keep it in sync.
-
-## Names, labels, language & forms
-- Icon-only controls have an `aria-label` sourced from i18n
-  (`accessibility.*`), never a hard-coded string.
-- All `<img>`/`<NuxtImg>` have meaningful `alt` (empty `alt=""` only for
-  purely decorative images).
-- Every form field has a programmatically associated `<label>`; group
-  related controls with `<fieldset>`/`<legend>`; errors are linked via
-  `aria-describedby` and announced, not colour-only.
-- Page/document language is correct per locale; add new strings to both
-  `i18n/locales/en.json` and `de.json`.
-
-## Visual & motion
-- Text/background contrast meets WCAG AA (4.5:1, or 3:1 for large text);
-  verify against Tailwind tokens in `assets/css/tokens.css`.
-- Animations/transitions respect `prefers-reduced-motion` (covered globally
-  in `tokens.css` — do not reintroduce unconditional long transitions).
-- Tap targets are at least 24x24 px.
-
-## Verification (automated + manual)
-- Run `pnpm lint` (eslint-plugin-vuejs-accessibility is wired in).
-- For page-level changes, run `pnpm seo:lighthouse` and keep the
-  `categories:accessibility` gate (error, minScore 0.9) green.
-- web.dev review method: also do a manual pass — keyboard-only walk of
-  the changed flow and an accessibility-tree/contrast check in DevTools;
-  automated tools catch only a subset.

 ## Constraints
 - Do not add new dependencies or config presets without clear justification.
 - Respect the existing directory structure; extend, don't rearrange.

-  Diagnose and fix Lighthouse "Best Practices" failures on this Nuxt 4 site

-
-# Lighthouse Best Practices Review (Nuxt 4 / Cloudflare)
-
-Current best-practices score is ~0.73 (CI gate is `warn`, minScore 0.9 —
-keep it green, do not let it regress further). The failing audits and the
-fix patterns for this repo:
-
-## Console errors (`errors-in-console`)
-
-Two known errors:
-
-- **`net::ERR_CERT_AUTHORITY_INVALID`** — a resource is loaded over a
-  host with an invalid/untrusted certificate. Find the offending request
-  (analytics proxy, image/CDN host, embed) and serve it from a valid-cert
-  origin or the first-party proxy. Never ship mixed/invalid-cert requests.
-- **`Hydration completed but contains mismatches`** — SSR markup differs
-  from client render. Common causes here: `Date`/locale/random values
-  rendered without `<ClientOnly>`, `import.meta.client` branching in
-  templates, i18n/`useState` not seeded on the server, or
-  browser-only APIs read during setup. Fix the markup-divergence at the
-  source; do not silence it. Zero console errors/warnings is the bar.
-
-## Third-party cookies (`third-party-cookies`)
-
-`NID` (Google) and PostHog cookies are set unconditionally. Fixes:
-
-- Gate `nuxt-gtag` and `nuxt-posthog` initialisation behind explicit
-  cookie consent; do not set analytics cookies before opt-in.
-- Prefer first-party proxying (PostHog `proxy: true` is already set —
-  keep analytics requests same-origin) and cookieless/consentless modes
-  where the vendor supports them.
-- This audit overlaps with the `lighthouse-perf` deferral work — deferring
-  + consent-gating analytics fixes both at once.
-
-## Back/forward cache (`bf-cache`)
-
-"Navigation was cancelled before the page could be restored." Avoid
-`unload` listeners, keep `Cache-Control: no-store` off HTML responses, and
-do not hold open connections that block bfcache. Verify in Chrome DevTools
-→ Application → Back/forward cache → "Test".
-
-## Missing source maps (`valid-source-maps`)
-
-**Policy: never publish source maps to production.** Public `.map` files
-(or a `sourceMappingURL` pointing at a deployed URL) expose first-party
-source and are a security/IP concern, so this audit is **accepted as a
-deliberate trade-off** — do not "fix" it by serving source maps.
-
-If symbolicated stack traces are needed, generate **hidden** source maps
-in CI (no `sourceMappingURL` comment in the shipped bundle) and upload
-them privately to the error monitor; never deploy the `.map` files to
-Cloudflare or reference them from public assets. Do not enable a plain
-`sourcemap.client` that emits public maps in `nuxt.config.ts`.
-
-## Inspector / cookie issues (`inspector-issues`)
-
-Resolve the Chrome "Issues" panel entries (cookie attribute / deprecation
-warnings) surfaced by the same analytics scripts — usually fixed by the
-consent gating and first-party proxying above.
-
-## Verification (required)
-
-1. `pnpm build` must pass.
-2. `pnpm seo:lighthouse`; report the `best-practices` score and confirm
-   no audit listed above regressed.
-3. Manually confirm a clean console (no errors/warnings) and a passing
-   bfcache test in DevTools for any change touching scripts, cookies,
-   SSR, or hydration.

-name: lighthouse-perf
-description: >-
-  Diagnose and fix Lighthouse performance regressions on this Nuxt 4 site
-  (TBT, LCP, CLS, JS execution, third-party scripts, render-blocking). Use
-  whenever a page change can affect load/runtime cost, when adding scripts or
-  modules, or when the Lighthouse performance score drops — especially on the
-  mobile form factor, which CI does not yet cover.
----
-
-# Lighthouse Performance Review (Nuxt 4 / Cloudflare)
-
-CI (`.lighthouserc.json`) only runs the **desktop** preset. The known
-problem profile is **mobile**: TBT ~1.5 s, CLS ~0.28, TTI ~7.5 s while
-desktop is ~0.93. Always re-check mobile after changes — desktop green
-does not mean mobile is fine.
-
-Apply this checklist to changed `.vue`/`.ts` files under `pages/`,
-`components/`, `layouts/`, `plugins/`, and to `nuxt.config.ts`.
-
-## Third-party scripts (biggest TBT lever)
-
-The main-thread cost is dominated by PostHog (`nuxt-posthog`, including
-`surveys.js` / `posthog-recorder.js`) and Google Ads/gtag
-(`nuxt-gtag`, `gtag/js?id=AW-...`).
-
-- `nuxt-vitalizer` is installed and enabled but **unconfigured**. Configure
-  it (`disableStylesheets`/`prefetchLinks` and especially delayed/idle
-  hydration) before hand-rolling anything.
-- Defer non-critical third-party JS until idle or first interaction — never
-  load analytics/session-recording during initial render. Use
-  `useScriptEventPage`/Nuxt Scripts patterns, `requestIdleCallback`, or the
-  module's lazy/consent gate. PostHog session recording and surveys must
-  load **after** the page is interactive.
-- Consider PartyTown / web-worker offload for gtag if it cannot be deferred.
-- Gate analytics behind cookie consent — this also fixes the
-  best-practices cookie audit (see `lighthouse-best-practices` skill).
-- Never add a new third-party `<script>` without a deferral strategy and a
-  before/after mobile Lighthouse run.
-
-## JavaScript payload
-
-- Reduce unused JS: the largest first-party chunks (`_nuxt/*.js`) ship
-  ~75 KiB unused. Prefer dynamic `import()` / `defineAsyncComponent` and
-  route-level code splitting for below-the-fold and interaction-only code.
-- Minify: ensure no un-minified first-party JS ships in production builds.
-- Legacy JS: avoid transpilation/polyfills for already-supported syntax;
-  keep the build target modern.
-- FontAwesome: import only the specific icons used (tree-shaken via the
-  SVG core), never whole icon packs.
-
-## Render-blocking & LCP
-
-- `_nuxt/entry.*.css` is render-blocking. Keep critical CSS inlined and
-  defer the rest; do not add global CSS imports in `nuxt.config.ts` `css[]`
-  without justification.
-- Ensure the LCP element (hero text/image) is discoverable in the initial
-  HTML — no client-only wrapper, `fetchpriority="high"` on the LCP image,
-  and a correctly sized `<NuxtImg>` (the project uses the Cloudflare
-  provider, `avif`/`webp`, quality 75).
-
-## CLS
-
-- The current culprit is the `<footer>` (`components/features/footer/Footer.vue`)
-  shifting layout late (mobile CLS 0.28). Reserve space for
-  late-loading/async content: fixed dimensions or `min-h-*` on images,
-  embeds, and any block whose content arrives after hydration.
-- Never insert content above existing content after load. Web fonts must
-  not cause reflow (`font-display: swap` + size-adjust, or self-host).
-
-## Verification (required)
-
-1. `pnpm build` must pass.
-2. `pnpm seo:lighthouse` (desktop gate) must stay green.
-3. For any change touching scripts, hydration, images, or layout, run a
-   **mobile** Lighthouse pass locally (`lighthouse <url>
-   --preset=... --form-factor=mobile`, or Chrome DevTools mobile) and
-   report before/after TBT, LCP, CLS, TTI. Do not claim a perf fix without
-   the mobile numbers.

-  Audit changes against web.dev network/loading guidance for this Nuxt 4
-  / Cloudflare site — cache lifetimes, preconnect/preload/priority hints,
-  compression, request ordering and the critical request chain. Use when
-  touching asset loading, fonts, images, third-party origins, or
-  Nitro/Cloudflare caching config.
----
-
-# Network & Caching Review (web.dev "Fast" — loading)
-
-The Lighthouse report flagged inefficient cache lifetimes (~79 KiB),
-render-blocking CSS, a non-trivial network dependency tree and (mobile)
-LCP request discovery. Apply to changed `nuxt.config.ts`, `routeRules`,
-`server/`, fonts/`assets/css/`, and components adding external origins.
-
-## Caching
-- Static hashed assets (`/_nuxt/*`) get long-lived immutable caching;
-  HTML stays short/revalidated (and `Cache-Control: no-store` is *not*
-  set — that also breaks bfcache, see `lighthouse-best-practices`).
-- Set cache headers via Nitro `routeRules`, leveraging the Cloudflare
-  edge — uniform, not per-component.
-
-## Connection setup
-- `preconnect` (with `crossorigin` where credentialed) to required
-  third-party origins actually on the critical path (PostHog proxy,
-  Cloudflare image host) — no speculative preconnects to unused origins.
-- `dns-prefetch` only as a progressive fallback.
-
-## Priority & critical chain
-- LCP image: `fetchpriority="high"`, discoverable in initial HTML, no
-  lazy-loading above the fold. Below-the-fold media: `loading="lazy"`.
-- `preload` only genuinely critical resources (LCP image, critical
-  font); never preload everything (defeats prioritisation).
-- Keep the critical request chain shallow — avoid CSS/JS that imports
-  more blocking CSS/JS; defer non-critical CSS.
-
-## Fonts & compression
-- Fonts: `font-display: swap`, `preload` the one critical face, prefer
-  self-host/woff2 with size-adjust to avoid CLS.
-- Ensure Brotli/gzip is in effect at the Cloudflare edge for text assets.
-
-## Verification
-- `pnpm build` passes; `pnpm seo:lighthouse` not regressed.
-- Inspect the Network panel (and a mobile Lighthouse run): confirm cache
-  headers, no redundant preconnects, and the LCP resource is requested
-  early with high priority. Report before/after LCP for loading changes.

-
-## Consent gating
-- No analytics/marketing cookie or network call before explicit opt-in.
-  `nuxt-gtag` and `nuxt-posthog` must initialise only after consent;
-  default state is "no tracking".
-- Consent choice is persisted (first-party) and revocable; revoking
-  stops collection and clears vendor cookies.
-- Strictly-necessary cookies (i18n `i18n_redirected`, consent itself)
-  are exempt and must stay functional without consent.
-
-## Data minimisation
-- Keep PostHog `proxy: true` so analytics is same-origin; do not add
-  vendors that bypass the proxy.
-- Collect the minimum: avoid PII in event properties; respect
-  `anonymize_ip` (already set for gtag) and PostHog masking for session
-  recording. Do not enable session recording/surveys before consent.
-- New third-party embed/script → document what data it sees and why.
-
-## Transparency
-- Any new data flow is reflected in the privacy page content
-  (`content/`), and the cookie/consent UI lists the actual vendors.
-
-## Verification
-- `pnpm build` passes.
-- Manually confirm in DevTools (Application → Cookies / Network) that a
-  fresh visit with no consent sets **no** analytics cookies and makes
-  **no** tracking requests; tracking begins only after opt-in.

 ## Reusable Agents & Skills (`.claude/`)
 These are checked in so every CLI/web session gets the same standards. Treat
 them as rules, not suggestions:
+**Atomic principle:** every skill addresses exactly one topic and has a
+matching single-topic reviewer agent named `<skill>-reviewer`. Apply the
+skill while making the change; delegate the matching reviewer before the
+PR. Use only the skills/agents the change actually touches.
+
 - **`.claude/skills/component-scaffold`** — MUST be followed when adding any
-  new feature/section/page (types → composables → sections → page).
-- **`.claude/skills/a11y-review`** — MUST be run on every changed
-  `components/`, `layouts/`, or `pages/` file before finishing UI work.
-- **`.claude/agents/accessibility-reviewer`** — delegate an independent
-  accessibility pass to this subagent before opening a PR with visual changes.
-- **`.claude/skills/lighthouse-perf`** — MUST be applied when a change can
-  affect load/runtime cost (scripts, modules, images, hydration, layout).
-  Note: CI only runs the **desktop** Lighthouse preset; mobile is the known
-  weak spot (TBT/CLS/TTI) and must be checked manually.
-- **`.claude/skills/lighthouse-best-practices`** — MUST be applied when
-  touching third-party scripts, analytics, cookies, or SSR/hydration
-  (console errors, third-party cookies, bf-cache, source maps).
-- **`.claude/agents/lighthouse-performance-reviewer`** — delegate an
-  independent performance + best-practices pass to this subagent before
-  opening a PR that touches scripts, analytics, images, or SSR/hydration.
-- **`.claude/agents/google-web-guidelines-reviewer`** — delegate an
-  independent review against Google's official web guidelines (Core Web
-  Vitals LCP/INP/CLS, Lighthouse Best Practices, web.dev) before such PRs.
-- **web.dev pillar skills + reviewers** (apply the skill when the change
-  touches the area; delegate the matching reviewer before the PR):
-  - **`.claude/skills/web-security`** / **`.claude/agents/web-security-reviewer`**
-    — web.dev "Safe": HTTPS, CSP/security headers, safe embeds, no
-    mixed/insecure content, dependency safety.
-  - **`.claude/skills/seo-discoverability`** / **`.claude/agents/seo-discoverability-reviewer`**
-    — web.dev "Discoverable": crawlability, metadata, canonical/hreflang,
-    structured data, sitemap/robots (keep SEO ≥ 0.95).
-  - **`.claude/skills/privacy-consent`** / **`.claude/agents/privacy-consent-reviewer`**
-    — consent-gated analytics, third-party data minimisation, GDPR
-    alignment for PostHog/gtag.
-  - **`.claude/skills/network-caching`** / **`.claude/agents/network-caching-reviewer`**

+  `perf-reduce-unused-js`, `perf-no-legacy-js`, `perf-minify-js`,
+  `perf-render-blocking-css`, `perf-lcp-element`,
+  `perf-cls-layout-stability`. CI runs the **desktop** preset only;
+  mobile (TBT/CLS/TTI) is the known weak spot — check it manually.
+- **Best Practices**: `bp-clean-console`, `bp-no-hydration-mismatch`,
+  `bp-bfcache`, `bp-no-prod-source-maps`.
+- **Network/Loading**: `net-cache-lifetimes`, `net-resource-hints`,
+  `net-critical-request-chain`, `net-font-loading`,
+  `net-text-compression`.
+- **Security ("Safe")**: `sec-no-mixed-content`, `sec-response-headers`,
+  `sec-content-security-policy`, `sec-safe-links-embeds`,
+  `sec-dependency-safety`.
+- **SEO ("Discoverable")**: `seo-page-metadata`,
+  `seo-canonical-hreflang`, `seo-crawlable-content`, `seo-indexability`,
+  `seo-structured-data` (keep SEO ≥ 0.95).
+- **Privacy**: `privacy-consent-gating`, `privacy-data-minimisation`,
+  `privacy-transparency`.
+- Each of the above has a `<name>-reviewer` agent under
+  `.claude/agents/` for an independent single-topic pass before the PR.
 - **Source maps are never published to production.** The Lighthouse
   `valid-source-maps` audit is an accepted trade-off; if symbolication is
   needed, generate hidden maps in CI and upload them privately — never

Subject: [PATCH 6/6] feat: close web.dev coverage gaps with 3 atomic
 skills/agents

web.dev cross-check found three uncovered topics (two also flagged in
the Lighthouse reports): perf-image-delivery (web.dev Performance
"Images" / image-delivery-insight), perf-main-thread-work (web.dev
"Web Workers" / INP, mainthread-work/bootup/TBT), and a11y-typography
(web.dev Accessibility "Typography"). Each adds a matching atomic
<skill>-reviewer agent; AGENTS.md updated.

+# Accessible Typography
+
+Single topic: text is readable for everyone (contrast itself lives in
+`a11y-contrast-motion`).
+
+- Body text uses relative units and is comfortably sized (no fixed tiny
+  `px`); respects user font-size settings.
+- Line length, `line-height`, and paragraph spacing aid readability;
+  don't justify body text.
+- Layout reflows without loss of content at 200% zoom / 320px width (no
+  horizontal scroll for text).
+- Don't convey meaning by typographic styling alone.
+
+Verify: zoom to 200% and narrow to 320px on changed views — content
+reflows, nothing clipped; `pnpm lint` clean.

+# Image Delivery
+
+Single topic: minimise image bytes without visible quality loss (report:
+`image-delivery-insight`, ~18-20 KiB).
+
+- Use `<NuxtImg>`/`<NuxtPicture>` with the Cloudflare provider; serve
+  `avif`/`webp` (config default, quality 75) — no raw `<img>` to large
+  source files.
+- Always set `width`/`height` (or aspect-ratio) so images don't shift
+  layout (ties to `perf-cls-layout-stability`).
+- Responsive `sizes`/`srcset` matched to the layout; never ship a
+  desktop-sized image to mobile.
+- Below-the-fold images `loading="lazy"`; the LCP image is **not** lazy
+  (see `perf-lcp-element`).
+
+Verify: `pnpm build`; mobile Lighthouse — `image-delivery-insight` /
+`uses-responsive-images` not regressed.

+Single topic: keep the main thread free so the page stays responsive
+(report: `mainthread-work-breakdown` 3.9 s, `bootup-time` 2.6 s,
+TBT 1520 ms, max-FID 560 ms). This is the Core Web Vital **INP** lever
+for first-party code (third-party deferral is `perf-defer-third-party-scripts`).
+
+- No long tasks (>50 ms) during load/interaction; break work into chunks
+  (`scheduler.yield`/`requestIdleCallback`) or move heavy/CPU work to a
+  **Web Worker**.
+- Keep client hydration cost low: avoid eager heavy components; prefer
+  server rendering and lazy/async client islands.
+- Event handlers do minimal synchronous work; debounce/throttle hot
+  paths; no layout thrash in handlers.
+
+Verify: `pnpm build`; mobile Lighthouse — report before/after TBT and
+main-thread/bootup time.
