+review:
+  strengths:
+  - 'All four attempt-1 weaknesses are directly and correctly addressed: a subtitle
+    now labels the value axis ("Customer Satisfaction Score (0–100)"), dotted leader
+    stubs reconnect nudged labels to their true marker positions in the densest score
+    clusters, ▲/▼ glyphs make the increase/decrease encoding CVD-safe independent
+    of color, and the legend column was narrowed (Fixed(150) → Fixed(105)) to cut
+    unused whitespace'
+  - 'Correct slopegraph structure: two vertical time-point axes labeled "2023 Survey"/"2024
+    Survey" with endpoint labels on both sides, matching the spec notes exactly'
+  - Semantic red/green color-coding for decrease/increase follows the Imprint style
+    guide's semantic-exception rule, and the exact hex values are identical across
+    both themes
+  - Theme-adaptive chrome correctly threaded through PAGE_BG/INK/INK_SOFT tokens —
+    both renders pass the light/dark legibility check with no dark-on-dark or light-on-light
+    failures
+  - 'Clean minimalist chrome: spines and default decorations fully hidden, no gridlines,
+    generous whitespace, subtle bold survey-year headers'
+  - 'Idiomatic Makie usage: GridLayout-based legend placement (fig[1,2] + colsize!)
+    with merge=true/unique=true, hidedecorations!/hidespines!, deterministic Random.seed!(42)'
+  - Entities sorted by descending 2023 score, giving the chart a clear top-to-bottom
+    rank ordering that aids scanning
+  weaknesses:
+  - Distinctive Makie-specific features are still underused — the chart relies on
+    generic primitives (lines!, scatter!, text!) that read as library-agnostic; leaning
+    on more Makie-specific machinery (e.g. Observables-driven layout tuning, a custom
+    recipe, richer Scene/Axis composition) would raise Library Mastery
+  - In the tightest score band (Video Conferencing 61.7 / Customer Portal 61.0 / Mobile
+    App 59.3 on the left; the 54.x/52.9 cluster at the bottom), label rows sit close
+    enough together that legibility could soften further at small preview sizes (~400px)
+    even though the anti-collision nudge keeps them technically non-overlapping at
+    full resolution
+  - Aesthetic sophistication is solid but still fairly close to a standard slopegraph
+    template — an additional refinement (e.g. subtle marker-size or opacity encoding
+    for magnitude of change) would push Design Excellence higher
+  image_description: |-
+    Light render (plot-light.png):
+      Background: Warm off-white, matches #FAF8F1, not pure white, not dark.
+      Chrome: Title "slope-basic · julia · makie · anyplot.ai" is bold, dark ink, centered at top, fully visible with no clipping. A new subtitle "Customer Satisfaction Score (0–100)" sits directly beneath it, correctly labeling what the y-values represent. "2023 Survey" / "2024 Survey" headers sit atop each vertical reference axis in medium-gray bold text. Ten product names + scores flank both axes in dark ink text, and the right-hand labels now carry ▲/▼ direction glyphs before each value. Thin dotted leader stubs connect nudged labels back to their true marker/line position wherever the anti-collision loop moved them. Legend ("Decrease" / "Increase") sits in a narrowed right-hand column, readable dark text on the light background.
+      Data: Ten diagonal lines connect 2023 to 2024 scores, colored matte red (#AE3030, decrease) or brand green (#009E73, increase), with small circular markers (cream stroke) at each endpoint.
+      Legibility verdict: PASS — all title, subtitle, header, label, and legend text is clearly readable against the light background; no light-on-light issues.
+
+    Dark render (plot-dark.png):
+      Background: Warm near-black, matches #1A1A17, not pure black, not light.
+      Chrome: Same title, subtitle, headers, and per-entity labels (including the ▲/▼ glyphs and leader stubs) now rendered in light ink (#F0EFE8 title / #B8B7B0 headers and subtitle), clearly legible against the dark surface. Legend text also flips to light ink.
+      Data: Same red (#AE3030) and green (#009E73) line/marker colors as the light render — confirmed identical data colors between themes, only chrome (background + text) flipped.
+      Legibility verdict: PASS — no dark-on-dark failures observed; all text (title, subtitle, headers, entity labels, legend) reads clearly against the near-black background. Brand green and matte red both remain clearly visible on the dark surface.
