feat: Full Spec Kit compliance implementation

Photo Management (per specs/photo-management.md):
- Sharp integration for 3-size compression (thumb/medium/full)
- WebP output with 80-90% quality
- Client-side compression with browser-image-compression
- PhotoUpload component with camera/drag-drop support
- Upload API with bulk support and stats endpoint

Testing:
- Backend: Jest tests for all major API endpoints
- Frontend: Vitest tests for utilities and API clients
- CI: Updated Forgejo workflow for test execution

Specs (100% coverage):
- visitor-management.md (Phase 8)
- messaging.md (Phase 9)
- audit-and-documents.md (Phase 10)
- accessibility-i18n.md (Phase 11)
- hardware-integration.md (Phase 12)
- advanced-features.md (Phase 13)

Documentation:
- OpenAPI 3.0 spec (docs/openapi.yaml)
- All endpoints documented with schemas

+# Feature Spec: Accessibility & Internationalization
+
+**Priority**: 🟢 Important  
+**Phase**: 11  
+**Status**: ✅ Implemented
+
+---
+
+## Overview
+
+Make the application accessible to all users regardless of ability or language. WCAG 2.1 AA compliance.
+
+---
+
+## Accessibility (a11y)
+
+### WCAG 2.1 AA Requirements
+
+#### Perceivable
+
+- [x] Text alternatives for images
+- [x] Color contrast ratio ≥ 4.5:1
+- [x] Text resizable to 200%
+- [x] Content reflows at 320px width
+
+#### Operable
+
+- [x] Full keyboard navigation
+- [x] Focus visible indicators
+- [x] Skip to main content link
+- [x] Touch targets ≥ 44x44px
+- [x] No keyboard traps
+
+#### Understandable
+
+- [x] Language attribute on HTML
+- [x] Consistent navigation
+- [x] Error identification
+- [x] Labels for form inputs
+
+#### Robust
+
+- [x] Valid HTML
+- [x] ARIA roles where needed
+- [x] Screen reader compatible
+
+### Implementation
+
+#### CSS Utilities
+
+```css
+.sr-only /* Screen reader only */
+.focus-visible /* Focus ring */
+.high-contrast /* High contrast mode */
+.reduced-motion /* Respects prefers-reduced-motion */
+```
+
+#### React Hooks
+
+- `usePrefersReducedMotion()` - Detect motion preference
+- `useFocusTrap(ref)` - Trap focus in modals
+
+#### Components
+
+- `VisuallyHidden` - Hide but keep in DOM
+- `SkipLink` - Skip to main content
+- `LiveRegion` - Announce to screen readers
+
+---
+
+## Internationalization (i18n)
+
+### Supported Languages
+
+1. English (en) - Default
+2. Spanish (es) - Primary translation
+
+### Implementation
+
+#### Library
+
+- `react-i18next` for translations
+- `i18next-browser-languagedetector` for auto-detection
+
+#### Translation Structure
+
+```
+/frontend/src/locales/
+├── en/
+│   └── translation.json
+└── es/
+    └── translation.json
+```
+
+#### Usage
+
+```tsx
+import { useTranslation } from 'react-i18next';
+
+function Component() {
+    const { t } = useTranslation();
+    return <h1>{t('dashboard.title')}</h1>;
+}
+```
+
+### Translation Keys
+
+#### Common
+
+- `common.save`, `common.cancel`, `common.delete`
+- `common.loading`, `common.error`
+- `common.yes`, `common.no`
+
+#### Navigation
+
+- `nav.dashboard`, `nav.tasks`, `nav.rooms`
+- `nav.batches`, `nav.supplies`
+
+#### Forms
+
+- `form.required`, `form.invalid`
+- `form.submit`, `form.cancel`
+
+---
+
+## User Preferences
+
+### PreferencesContext
+
+- `theme`: 'light' | 'dark' | 'system'
+- `language`: 'en' | 'es'
+- `fontSize`: 'small' | 'medium' | 'large'
+- `highContrast`: boolean
+- `reducedMotion`: boolean
+- `soundEnabled`: boolean
+- `notificationsEnabled`: boolean
+- `compactMode`: boolean
+
+### Persistence
+
+- Stored in localStorage
+- Synced across tabs
+- Applied on app load
+
+---
+
+## Testing
+
+### Accessibility Testing
+
+- Lighthouse accessibility audit
+- axe-core browser extension
+- Manual keyboard navigation test
+- Screen reader testing (VoiceOver, NVDA)
+
+### i18n Testing
+
+- All strings extracted to JSON
+- No hardcoded strings in components
+- RTL layout support (future)
