 ## Unreleased
 
+- **Redesigned startup welcome banner.** The banner now uses a cleaner footer-chip layout: the "What's new / Update available" chip sits on the panel's bottom border, the headline/strapline/help lines align beside the robot logo, and the info grid drops its vertical separator. The robot art and palette are unchanged.
+- **Terminal-aware rendering for minimal and CI terminals.** The shell UI adapts to the terminal — ASCII glyph fallbacks for `TERM=dumb` and legacy Windows code pages, reduced-motion mode (`PYTHINKER_REDUCED_MOTION`), and `NO_COLOR`/`CLICOLOR` support that strips color cleanly — so output stays readable in CI logs, SSH panes, and bare terminals.
 - **Windows updates avoid encoded PowerShell.** Native updates now launch the signed Inno installer directly with Restart Manager flags instead of a `powershell.exe -EncodedCommand` helper, reducing antivirus command-line heuristic false positives. Windows bootstrap installs use visible `/SILENT` progress instead of fully suppressed setup, and the installer build signs bundled PE files plus Inno's setup/uninstaller/temp copies when signing credentials are configured.

+# Product
+
+## Register
+
+Use a product-engineering register: concise, practical, and confident. Write for developers who value clear terminal workflows; prefer precise verbs, concrete outcomes, and short examples over marketing slogans.
+
+## Users
+
+Developers using Pythinker inside terminal workflows, including PowerShell, Windows Terminal, macOS Terminal, iTerm2, GNOME Terminal, CI logs, SSH sessions, and low-color or no-color shells. They are reviewing code, diagnosing failures, running commands, approving changes, and switching between AI and shell work.
+
+## Product Purpose
+
+Pythinker Code is a review-first AI engineering CLI. The interface should help users understand what the agent is doing, trust approvals and results, move quickly through repeated terminal actions, and keep context visible without leaving the shell.
+
+## Brand Personality
+
+Disciplined, terminal-native, precise.
+
+## Anti-references
+
+Do not make the TUI feel like a neon dashboard, glassmorphism mockup, emoji-heavy chat toy, or novelty terminal skin. Avoid fragile color-only semantics, excessive borders, box-heavy layouts, decorative motion, AI-purple gradients, and UI effects that slow repeated keyboard workflows.
+
+## Design Principles
+
+1. Standardize first: core structure, labels, states, and colors must behave consistently across shells and terminal capabilities.
+2. Text is the UI: layout, copy, hierarchy, and semantic labels should remain usable in no-color and narrow-width environments.
+3. Speed over spectacle: feedback should be immediate, short, and interruptible; repeated keyboard actions should not animate.
+4. State must be explicit: approvals, background work, errors, warnings, and tool execution need clear shape and wording, not just color.
+5. Compatibility is craft: PowerShell, Windows Terminal, Unix terminals, SSH, CI, and screen readers should all get a coherent experience.
+
+## Accessibility & Inclusion
+
+Target WCAG-minded contrast within ANSI limitations, colorblind-safe state semantics, reduced-motion behavior, keyboard-first operation, graceful no-color fallback, and responsive rendering from narrow split panes to wide terminals.
