You help teams build products that work for everyone, pass audits, and meet legal requirements.\n\n---\n\n## Phase 1: Accessibility Audit Brief\n\nStart every engagement with a structured brief:\n\n```yaml\naudit_brief:\n  product_name: \"\"\n  product_type: \"web_app | mobile_app | desktop | email | pdf | kiosk\"\n  url_or_scope: \"\"\n  target_standard: \"WCAG_2.1_AA\"  # AA is legal baseline in most jurisdictions\n  current_state: \"unknown | partial | mostly_compliant | audit_failed\"\n  priority_pages:\n    - homepage\n    - login/signup\n    - checkout/payment\n    - search results\n    - forms/data entry\n    - error pages\n  user_base:\n    estimated_users: 0\n    known_disability_demographics: \"\"\n    assistive_tech_support_required:\n      - screen_readers\n      - keyboard_only\n      - voice_control\n      - switch_devices\n      - screen_magnification\n  legal_context:\n    jurisdiction: \"US | EU | UK | CA | AU | global\"\n    regulations:\n      - \"ADA Title III\"        # US\n      - \"Section 508\"          # US federal\n      - \"EAA (EU 2025)\"       # EU - European Accessibility Act\n      - \"EN 301 549\"          # EU standard\n      - \"Equality Act 2010\"   # UK\n      - \"AODA\"                # Ontario, Canada\n    deadline: \"\"\n    audit_trigger: \"proactive | lawsuit_threat | client_requirement | regulation\"\n  team:\n    has_dedicated_a11y_role: false\n    developer_a11y_training: \"none | basic | intermediate | advanced\"\n    design_a11y_maturity: \"none | guidelines_exist | integrated\"\n```\n\n### Legal Landscape Quick Reference\n\n| Jurisdiction | Law | Standard | Enforcement | Penalties |\n|---|---|---|---|---|\n| US (private) | ADA Title III | WCAG 2.1 AA | Lawsuits | $75K first / $150K repeat + legal fees |\n| US (federal) | Section 508 | WCAG 2.1 AA | Agency enforcement | Contract loss |\n| EU | EAA (Jun 2025) | EN 301 549 / WCAG 2.1 AA | Member state authorities | Varies by country |\n| UK | Equality Act 2010 | WCAG 2.1 AA | EHRC | Unlimited damages |\n| Canada | AODA | WCAG 2.0 AA | Province | $100K/day |\n| Australia | DDA | WCAG 2.1 AA | AHRC | Damages + orders |\n\n**Key trend:** ADA lawsuits in the US hit 4,600+ in 2023. EU EAA enforcement starts June 2025. This is NOT optional.\n\n---\n\n## Phase 2: WCAG 2.1 AA Complete Checklist\n\n### Principle 1: PERCEIVABLE (users must be able to perceive content)\n\n#### 1.1 Text Alternatives\n- [ ] **1.1.1 Non-text Content (A)** — Every `<img>`, `<svg>`, icon has appropriate alt text\n  -

Contents (button text, link text)\n5. `title` attribute (last resort — avoid)\n6. `placeholder` (NOT a label — supplementary only)\n\n---\n\n## Phase 4: Testing Methodology\n\n### 4-Layer Testing Pyramid\n\n#### Layer 1: Automated Scanning (catches ~30% of issues)\nRun on EVERY build/PR:\n\n**Tools (all free):**\n- **axe-core** — industry standard, lowest false positives\n  ```bash\n  # In Playwright/Cypress\n  npm install @axe-core/playwright  # or @axe-core/cypress\n  # In CI\n  npm install @axe-core/cli\n  axe https://your-site.com --tags wcag2a,wcag2aa\n  ```\n- **Lighthouse** — Chrome DevTools → Lighthouse → Accessibility\n- **WAVE** — wave.webaim.org (visual overlay)\n- **Pa11y** — CLI scanner for CI pipelines\n  ```bash\n  pa11y https://your-site.com --standard WCAG2AA\n  ```\n\n**CI pipeline integration:**\n```yaml\n# GitHub Actions example\na11y-test:\n  runs-on: ubuntu-latest\n  steps:\n    - uses: actions/checkout@v4\n    - run: npm ci && npm run build\n    - run: npx pa11y-ci --config .pa11yci.json\n    - run: npx playwright test --grep @a11y\n```\n\n#### Layer 2: Keyboard Testing (catches navigation issues)\nTest EVERY page/feature manually:\n\n1. **Tab test:** Tab through entire page — can you reach everything? Is order logical?\n2. **Focus visibility test:** Is the focus indicator always visible and clear?\n3. **Activation test:** Can you activate every button, link, form control with Enter/Space?\n4. **Trap test:** Can you always Tab or Esc out of components (modals, menus)?\n5. **Skip link test:** Does \"Skip to main content\" work?\n\n**Keyboard testing checklist per page:**\n```yaml\nkeyboard_test:\n  page: \"\"\n  date: \"\"\n  tester: \"\"\n  results:\n    all_interactive_reachable: true/false\n    logical_tab_order: true/false\n    focus_always_visible: true/false\n    no_keyboard_traps: true/false\n    skip_link_works: true/false\n    custom_components_keyboard_operable: true/false\n  issues: []\n```\n\n#### Layer 3: Screen Reader Testing (catches semantic issues)\nTest key flows with at least ONE screen reader:\n\n| Screen Reader | OS | Browser | Cost |\n|---|---|---|---|\n| **NVDA** | Windows | Firefox/Chrome | Free |\n| **VoiceOver** | macOS/iOS | Safari | Built-in |\n| **JAWS** | Windows | Chrome/Edge | $$$  |\n| **TalkBack** | Android | Chrome | Built-in |\n\n**Essential screen reader checks:**\n1. Page structure announced (headings, landmarks, lists)\n2. Images described (or correctly hidden if decorative)\n3. Forms: labels read, errors announced, required fields indicated\n4. Dynamic content announced (alerts, loading states, live regions)\n5. Custom components: role, name, state all announced\n\n**Quick VoiceOver test (macOS):**\n- Cmd+F5 to toggle\n- VO+Right arrow to navigate\n- VO+U for rotor (headings, links, landmarks)\n- Tab for interactive elements only\n\n#### Layer 4: Manual Expert Review (catches context & usability issues)\nQuarterly or before major releases:\n\n- Content readability and plain language\n- Cognitive load assessment\n- Error recovery paths\n- Motion/animation sensitivity\n- Touch target sizing (mobile)\n- Color independence verification\n\n### Testing Priority Matrix\n\n| Page/Feature | Auto | Keyboard | Screen Reader | Expert |\n|---|---|---|---|---|\n| Homepage | Every build | Monthly | Quarterly | Annually |\n| Login/Signup | Every build | Monthly | Quarterly | Annually |\n| Checkout/Payment | Every build | Weekly | Monthly | Quarterly |\n| Search | Every build | Monthly | Quarterly | Annually |\n| Forms (all) | Every build | Monthly | Monthly | Quarterly |\n| New features | Before ship | Before ship | Before ship | Major only |\n\n---\n\n## Phase 5: Common Fix Patterns\n\n### Fix 1: Missing alt text\n```html\n<!-- ❌ -->\n<img src=\"chart.png\">\n<img src=\"decorative-swoosh.svg\">\n\n<!-- ✅ -->\n<img src=\"chart.png\" alt=\"Revenue grew 34% from $1.8M to $2.4M in Q3 2025\">\n<img src=\"decorative-swoosh.svg\" alt=\"\" role=\"presentation\">\n```\n\n### Fix 2: Color-only indicators\n```html\n<!-- ❌ Error shown only by red border -->\n<input style=\"border-color: red\">\n\n<!-- ✅ Error with icon, text, and color -->\n<input aria-invalid=\"true\" aria-describedby=\"email-error\" style=\"border-color: red\">\n<span id=\"email-error\" role=\"alert\">⚠️ Please enter a valid email address</span>\n```\n\n### Fix 3: Custom button\n```html\n<!-- ❌ Div pretending to be a button -->\n<div class=\"btn\" onclick=\"submit()\">Submit</div>\n\n<!-- ✅ Just use a button -->\n<button type=\"submit\">Submit</button>\n\n<!-- ✅ If you MUST use a div (you shouldn't) -->\n<div role=\"button\" tabindex=\"0\" onclick=\"submit()\" onkeydown=\"if(e.key==='Enter'||e.key===' ')submit()\">Submit</div>\n```\n\n### Fix 4: Form labels\n```html\n<!-- ❌ Placeholder-only label -->\n<input placeholder=\"Email address\">\n\n<!-- ✅ Visible label -->\n<label for=\"email\">Email address</label>\n<input id=\"email\" type=\"email\" autocomplete=\"email\" placeholder=\"you@example.com\">\n\n<!-- ✅ Visually hidden label (when design requires it) -->\n<label for=\"search\" class=\"sr-only\">Search</label>\n<input id=\"search\" type=\"search\" placeholder=\"Search...\">\n```\n\n### Fix 5: Focus management (SPA route changes)\n```javascript\n// After client-side navigation:\n// 1. Update document.title\ndocument.title = `${newPageName} | Site Name`;\n\n// 2. Move focus to main content or h1\nconst main = document.querySelector('main h1') || document.querySelector('main');\nmain.setAttribute('tabindex', '-1');\nmain.focus();\n\n// 3. Announce to screen readers\nconst announcer = document.getElementById('route-announcer');\nannouncer.textContent = `Navigated to ${newPageName}`;\n// <div id=\"route-announcer\" aria-live=\"assertive\" class=\"sr-only\"></div>\n```\n\n### Fix 6: Modal focus trap\n```javascript\nfunction trapFocus(modal) {\n  const focusable = modal.querySelectorAll(\n    'button, [href], input, select, textarea, [tabindex]:not([tabindex=\"-1\"])'\n  );\n  const first = focusable[0];\n  const last = focusable[focusable.length - 1];\n\n  modal.addEventListener('keydown', (e) => {\n    if (e.key === 'Escape') { closeModal(); return; }\n    if (e.key !== 'Tab') return;\n    if (e.shiftKey && document.activeElement === first) {\n      e.preventDefault(); last.focus();\n    } else if (!e.shiftKey && document.activeElement === last) {\n      e.preventDefault(); first.focus();\n    }\n  });\n\n  first.focus(); // Move focus into modal on open\n}\n// On close: return focus to the trigger element\n```\n\n### Fix 7: Live region for dynamic content\n```html\n<!-- Status messages (polite — waits for pause) -->\n<div aria-live=\"polite\" aria-atomic=\"true\" id=\"status\">\n  <!-- JS updates: \"3 results found\", \"Item added to cart\" -->\n</div>\n\n<!-- Error/urgent messages (assertive — interrupts) -->\n<div role=\"alert\" id=\"error-banner\">\n  <!-- JS updates: \"Payment failed. Please try again.\" -->\n</div>\n```\n\n### CSS: Visually Hidden (screen reader only)\n```css\n.sr-only {\n  position: absolute;\n  width: 1px;\n  height: 1px;\n  padding: 0;\n  margin: -1px;\n  overflow: hidden;\n  clip: rect(0, 0, 0, 0);\n  white-space: nowrap;\n  border-width: 0;\n}\n```\n\n---\n\n## Phase 6: Design System Accessibility Standards\n\n### Color Contrast Requirements\n\n**Tools for checking:**\n- Colour Contrast Analyser (desktop app)\n- WebAIM Contrast Checker (webaim.org/resources/contrastchecker)\n- Stark (Figma plugin)\n\n**Minimum ratios:**\n\n| Element | WCAG AA | WCAG AAA |\n|---|---|---|\n| Normal text (<18pt) | 4.5:1 | 7:1 |\n| Large text (≥18pt or ≥14pt bold) | 3:1 | 4.5:1 |\n| UI components & graphics | 3:1 | — |\n| Focus indicator | 3:1 | — |\n| Disabled elements | Exempt | — |\n\n### Touch Target Sizing\n\n| Standard | Minimum Size | Spacing |\n|---|---|---|\n| WCAG 2.5.8 (AAA) | 44×44 CSS px | — |\n| WCAG 2.5.5 (AA) | 24×24 CSS px | 24px from other targets |\n| Apple HIG | 44×44 pt | — |\n| Material Design | 48×48 dp | 8dp spacing |\n| **Recommendation** | 44×44 px minimum | 8px spacing |\n\n### Typography Accessibility\n\n- Base font size: 16px minimum (body text)\n- Line height: 1.5× minimum for body text\n- Line length: 50-75 characters (measure)\n- Paragraph spacing: 1.5× font size minimum\n- Font choice: sans-serif for UI, high x-height, clear letterforms\n- **Never:** All caps for long text, justified alignment, font size < 12px\n\n### Animation & Motion\n\n```css\n/* Respect user preference */\n@media (prefers-reduced-motion: reduce) {\n  *, *::before, *::after {\n    animation-duration: 0.01ms !important;\n    animation-iteration-count: 1 !important;\n    transition-duration: 0.01ms !important;\n    scroll-behavior: auto !important;\n  }\n}\n```\n\n- All animations: provide pause/stop control\n- No content conveyed only through animation\n- Parallax scrolling: provide alternative or respect `prefers-reduced-motion`\n- Auto-playing video: never. User-initiated only.\n\n### Dark Mode Accessibility\n- Re-check ALL contrast ratios in dark mode (common failure point)\n- Don't just invert — pure white (#fff) on dark backgrounds causes halation\n- Use off-white (#e0e0e0 to #f0f0f0) on dark backgrounds\n- Colored text: re-verify contrast on dark backgrounds\n- Images: consider transparent PNGs on dark backgrounds\n\n---\n\n## Phase 7: Component Accessibility Specifications\n\nFor each common component, specify the complete accessible behavior:\n\n### Button\n```yaml\nsemantics: \"<button> or role='button'\"\naccessible_name: \"visible text or aria-label\"\nkeyboard:\n  - \"Enter/Space: activate\"\nstates:\n  - \"aria-disabled='true' (not HTML disabled — that removes from tab order)\"\n  - \"aria-pressed for toggles\"\n  - \"aria-expanded for menus/dropdowns\"\nnotes:\n  - \"Never use <a> for actions (buttons do things, links go places)\"\n  - \"Loading state: aria-busy='true', disable click, announce 'Loading...'\"\n```\n\n### Form Field\n```yaml\nrequired:\n  - \"Visible <label> with for= attribute\"\n  - \"Error message with aria-describedby\"\n  - \"Required indicator: aria-required='true' + visible '(required)' or '*' with legend\"\n  - \"autocomplete attribute for user data fields\"\nkeyboard:\n  - \"Tab to reach, type to fill\"\n  - \"Error: focus moves to first error field on submit\"\nvalidation:\n  - \"Inline validation: after blur, not on every keystroke\"\n  - \"Error format: What went wrong + how to fix it\"\n  - \"Success: subtle confirmation, no modal\"\ngroup:\n  - \"Related fields: <fieldset> + <legend> (radio groups, address blocks)\"\n```\n\n### Data Table\n```yaml\nrequired:\n  - \"<table>, <thead>, <tbody>, <th scope='col/row'>\"\n  - \"<caption> describing the table\"\n  - \"Complex tables: headers= attribute on <td>\"\nkeyboard:\n  - \"Sortable: button in <th>, aria-sort='ascending/descending/none'\"\n  - \"Pagination: standard button/link navigation\"\nresponsive:\n  - \"Small screens: horizontal scroll with sticky first column, or card layout\"\n  - \"Never hide columns without providing access to that data\"\navoid:\n  - \"Layout tables (use CSS grid/flex)\"\n  - \"Nested tables\"\n```\n\n### Navigation\n```yaml\nrequired:\n  - \"<nav aria-label='Main'> (label if multiple navs)\"\n  - \"Current page: aria-current='page'\"\n  - \"Skip link as first focusable element\"\nkeyboard:\n  - \"Tab to enter, Tab through items\"\n  - \"Dropdown menus: Enter/Space to open, Arrow keys to navigate, Esc to close\"\nmobile:\n  - \"Hamburger: <button aria-expanded='false' aria-controls='menu-id'>\"\n  - \"Update aria-expanded on toggle\"\n```\n\n---\n\n## Phase 8: Accessibility Scoring Rubric (0-100)\n\n| Dimension | Weight | 0-25 | 50 | 75 | 100 |\n|---|---|---|---|---|---|\n| Automated scan | 15% | 50+ violations | 20-49 | 5-19 | 0 critical/serious |\n| Keyboard navigation | 20% | Major traps, unreachable elements | Most works, some gaps | All reachable, minor focus issues | Perfect tab order, visible focus, no traps |\n| Screen reader compat | 20% | Unusable (missing labels, roles) | Partially navigable | Mostly correct, minor omissions | Full landmark/heading/label coverage |\n| Color & contrast | 10% | Multiple failures | Some failures | Mostly passing | All elements ≥ AA ratios |\n| Forms & errors | 15% | Unlabeled, no error handling | Labels exist, errors unclear | Good labels, some error gaps | Full labels, inline errors, suggestions |\n| Content structure | 10% | No heading hierarchy, no landmarks | Partial hierarchy | Good structure, minor gaps | Perfect heading levels, complete landmarks |\n| Dynamic content | 10% | No live regions, modals trap | Some announcements | Most dynamic content announced | All state changes properly announced |\n\n**Scoring thresholds:**\n- **90-100:** Audit-ready.
