+## ♿ Accessibility
+
+TypoGenie targets **WCAG 2.2 AAA** conformance across the entire application - both the app interface and the documents it generates. Accessibility is enforced at runtime, not bolted on after the fact.
+
+### Visual & Perception
+
+| Feature | Detail |
+|---------|--------|
+| **Color Contrast** | All text meets 7:1 contrast ratio (AAA) against zinc-950 backgrounds. Template colors are auto-corrected at render time via `ensureContrast()` - large text (18pt+/14pt+ bold) enforces 4.5:1, body text enforces 7:1 |
+| **Focus Indicators** | 2px indigo focus ring at 80% opacity, visible on all dark backgrounds. Meets 3:1 contrast requirement for non-text UI |
+| **Reduced Motion** | Global CSS `prefers-reduced-motion` disables all animations and transitions. Framer Motion animations individually gated via `useReducedMotion()` hook |
+| **Forced Colors** | Windows High Contrast Mode supported via `@media (forced-colors: active)` rules |
+| **Zoom Support** | Root font size set to `100%` (not `px`) so browser zoom and text scaling work correctly. `overflow-x: hidden` (not `overflow: hidden`) allows content access at 200%+ zoom |
+| **Text Spacing** | Line-height enforced at minimum 1.5 for body text, 1.0 for headings. Justified text overridden to left-aligned at render time (WCAG 1.4.8) |
+
+### Keyboard Navigation
+
+| Feature | Detail |
+|---------|--------|
+| **Full Keyboard Access** | Every interactive element is reachable and operable via keyboard. Logo uses `<button>`, not `<div>` |
+| **Skip Navigation** | "Skip to main content" link in index.html, visible on focus |
+| **Style Card Listbox** | Cards implement ARIA listbox pattern (`role="listbox"`/`role="option"`) with arrow key navigation, Enter/Space selection, and `aria-selected` state |
+| **Modal Focus Trapping** | All three modals use native `<dialog>` element - focus trap, Escape to close, and focus restoration handled natively by the browser |
+| **Shortcut Scoping** | Single-character shortcuts (`?`/`/`) are scoped to non-input contexts so they don't intercept typing in search or other fields |
+| **Target Sizes** | All interactive controls meet 44x44px minimum touch/click target (WCAG 2.5.5 AAA) |
+| **Iframe Keyboard Safety** | Preview iframes set to `tabIndex={-1}` so keyboard focus doesn't get trapped in non-interactive content |
+
+### Screen Reader Support
+
+| Feature | Detail |
+|---------|--------|
+| **Landmarks** | `<main id="main-content">`, `<nav aria-label="Style filters">`, `<nav aria-label="Progress">`, `<section aria-label="Style list">`, `<section aria-label="Style preview">` |
+| **Live Regions** | Screen readers announce state transitions (upload/configure/generate/preview), search result counts, loading states, export success/failure |
+| **Semantic Markup** | Progress stepper uses `<nav><ol>` with `aria-current="step"`. Keyboard shortcuts list uses `<dl>/<dt>/<dd>`. Decorative elements marked `aria-hidden="true"` |
+| **Modal Accessibility** | All dialogs have `aria-labelledby` pointing to their heading. Export options use `<fieldset>/<legend>` for radio groups |
+| **Dynamic Labels** | Favorite button announces "Add/Remove [style name] from favorites" with `aria-pressed` state. Category and paper size filters expose `aria-pressed` toggle state |
+| **Accessible Names** | Every icon-only button has an `aria-label`. All decorative icons carry `aria-hidden="true"` |
+| **Error Handling** | Errors use `role="alert"` (no conflicting `aria-live`). File upload errors linked to dropzone via `aria-describedby`. No auto-dismissing error messages |
+| **Error Boundary** | Application-level `ErrorBoundary` component catches crashes and renders an accessible `role="alert"` error screen with a reload option |
+
+### Accessible Document Output
+
+The `.docx` files TypoGenie generates are also built with accessibility in mind:
+
+| Feature | Detail |
+|---------|--------|
+| **Document Metadata** | Every exported DOCX includes `title`, `description`, and `creator` properties for assistive technology |
+| **Heading Structure** | Semantic `HeadingLevel` preserved in both rendering modes (semantic and high-fidelity table layout) |
+| **Table Headers** | Rows containing `<th>` elements are marked with `tableHeader: true` so screen readers can announce column/row headers |
+| **Image Placeholders** | `<img>` elements in Markdown are converted to italic `[Image: alt text]` placeholders rather than silently dropped |
+| **Contrast-Safe Colors** | All template text colors are validated and auto-corrected against their backgrounds before being applied to the document |
+
+### Runtime Contrast Validation
+
+Template colors are never trusted blindly. At CSS generation time, every text/background color pair passes through `ensureContrast()`:
+
+```
+Template says text color = #555555 on background #1a1a1a
+→ contrastRatio("#555555", "#1a1a1a") = 2.8:1 (fails 7:1 AAA)
+→ ensureContrast() lightens to #9a9a9a = 7.1:1 (passes)
+→ Rendered color = #9a9a9a
+```
+
+This means all 165+ styles automatically meet WCAG AAA contrast requirements regardless of their original color definitions. The original aesthetic is preserved as closely as possible while guaranteeing readability.
