+## ♿ Accessibility (WCAG 2.2 AAA)
+
+Whisper Voice is built to be usable by everyone. The entire interface has been engineered to meet **WCAG 2.2 AAA** — the highest tier of accessibility compliance. This is not a checkbox exercise; it is a structural commitment.
+
+### Color & Contrast
+Every design token is calibrated for **Enhanced Contrast** (WCAG 1.4.6, 7:1 minimum):
+
+| Token | Ratio | Purpose |
+| :--- | :--- | :--- |
+| `textPrimary` #FAFAFA | ~17:1 | Body text, headings |
+| `textSecondary` #ABABAB | 8.1:1 | Descriptions, hints |
+| `accentPurple` #B794F6 | 7.2:1 | Interactive elements, focus rings |
+| `borderSubtle` | 3:1 | Non-text contrast for borders and separators |
+
+### Keyboard Navigation
+Full keyboard access — no mouse required:
+
+*   **Tab / Shift+Tab**: Navigate between all interactive controls (sliders, switches, buttons, dropdowns, text fields).
+*   **Arrow Keys**: Navigate the Settings sidebar tabs.
+*   **Enter / Space**: Activate any focused control.
+*   **Focus Rings**: Every interactive element shows a visible 2px accent-colored focus indicator.
+
+### Screen Reader Support
+Every component is annotated with semantic roles and descriptive names:
+
+*   Buttons, sliders, checkboxes, combo boxes, text fields — all declare their `Accessible.role` and `Accessible.name`.
+*   Switches report "on" / "off" state in their accessible name.
+*   The loader status uses `AlertMessage` for live-region announcements.
+*   Settings tabs use `Tab` / `PageTab` roles matching WAI-ARIA patterns.
+
+### Non-Color State Indicators
+Toggle switches display **I/O marks** inside the thumb (not just color changes), ensuring state is perceivable without color vision (WCAG 1.4.1).
+
+### Target Sizes
+All interactive controls meet the **24px minimum** target size (WCAG 2.5.8). Slider handles, buttons, switches, and nav items are all comfortably clickable.
+
+### Reduced Motion
+A **Reduce Motion** toggle (Settings > Visuals) disables all decorative animations:
+
+*   Shader effects (gradient blobs, glow, CRT scanlines, rainbow waveform)
+*   Particle systems
+*   Pulsing animations (mic button, recording timer, border)
+*   Loader logo pulse and progress shimmer
+
+The system also respects the **Windows "Show animations" preference** via `SystemParametersInfo` detection. Essential information (recording state, progress bars, timer text) remains fully functional.
