16084c414d refactor: Unify all settings into single Save Preferences button
Simplified the settings page by consolidating all save buttons into one
global "Save Preferences" button at the bottom of the page.

## Changes Made

### Unified Save Handler
- Merged `handleSaveProfile` and `handleSavePreferences` into single `handleSaveAll` function
- Single save handler now updates:
  * Profile name
  * Timezone
  * Time format (12h/24h)
  * Notification preferences
- One API call to save all settings at once

### Removed Individual Save Buttons
- Removed "Save Profile" button from Profile Information section
- Removed "Save Preferences" button from Preferences section
- Removed "Save Notification Settings" button from Notifications section

### Added Global Save Button
- Centered "Save Preferences" button at bottom of settings
- Positioned above Account Actions (Logout) section
- Large, prominent button (minWidth: 200px)
- Single source of truth for all settings changes

### User Experience Benefits
- **Simpler**: One clear action to save all changes
- **Fewer clicks**: No need to save each section separately
- **Clear feedback**: Single success/error message for all updates
- **Better UX**: Users can make multiple changes and save once
- **Consistent**: All settings treated as unified preferences

Files changed: 1 file (settings page)

c27f72e41d refactor: Consolidate settings page save buttons for better UX
Improved the settings page by removing individual save buttons from each
preference component and adding unified save buttons per section:

## Changes Made

### Component Updates
- **TimeZoneSelector**: Converted to controlled component with value/onChange props
  * Removed internal state management and save button
  * Removed success/error alerts (now handled by parent)
  * Added auto-detect as simple button without save

- **TimeFormatSelector**: Converted to controlled component with value/onChange props
  * Removed internal state management and save button
  * Removed success/error alerts (now handled by parent)
  * Simplified to just radio buttons with preview

### Settings Page Improvements
- Added timezone and timeFormat to local state
- Created separate save handlers:
  * `handleSaveProfile` - for name/email changes
  * `handleSavePreferences` - for timezone and time format
- Three clear sections with dedicated save buttons:
  1. **Profile Information** → "Save Profile" button
  2. **Preferences** (Language, Units, Timezone, Time Format) → "Save Preferences" button
  3. **Notifications** → "Save Notification Settings" button

### User Experience Benefits
- Clearer separation between different types of settings
- Single save action per logical section instead of multiple buttons
- Consistent save pattern across all settings cards
- Reduced visual clutter with fewer buttons on page
- Better organization: related settings grouped with one save action

Files changed: 3 files (TimeZoneSelector, TimeFormatSelector, settings page)

  * Time format (12h with AM/PM or 24h)

## Settings Page Updates
- Added TimeZoneSelector to Preferences card
- Added TimeFormatSelector to Preferences card
- Visual separators (Dividers) between preference sections
- Settings now show: Language | Units | Timezone | Time Format

## Translations

## User Experience Flow
1. User registers → timezone auto-detected and saved
2. User can change timezone in Settings > Preferences > Time Zone
3. User can change time format in Settings > Preferences > Time Format
4. All dates/times throughout app respect these preferences
5. Changes persist across sessions

Implemented comprehensive frontend localization infrastructure supporting
5 languages (English, Spanish, French, Portuguese, Chinese) with measurement
unit preferences (Metric/Imperial). This lays the foundation for international
user support.

**Core Infrastructure:**
- Installed i18next, react-i18next, i18next-browser-languagedetector
- Created I18nProvider component integrated into app layout
- Configured i18next with language detection and localStorage persistence
- Created 35 translation files (5 languages × 7 namespaces)

**Translation Namespaces:**
- common: App-wide UI elements, navigation, actions
- tracking: Activity tracking (feeding, sleep, diaper, milestones)
- ai: AI assistant chat interface
- auth: Authentication flows (login, signup, password reset)
- settings: Settings and preferences
- onboarding: Onboarding flow
- errors: Error messages and validation

**Custom Hooks:**
- useTranslation: Type-safe translation wrapper
- useLocale: Language and measurement system management
- useFormatting: Date, time, number, and unit formatting

**Measurement Unit Support:**
- Created unit conversion utilities (weight, height, temperature, volume)
- Metric: kg, cm, °C, ml
- Imperial: lb, in, °F, oz
- Bidirectional conversion functions

**UI Components:**
- LanguageSelector: Dropdown to change app language
- MeasurementUnitSelector: Toggle between Metric/Imperial
- Integrated both into Settings page Preferences section

**Next Steps (Remaining):**
- Add measurement preferences to backend user schema
- Create onboarding flow with language/measurement selection
- Apply translations to existing components (dashboard, tracking forms)
- Implement multi-language AI responses
- Add professional translations (currently using basic translations)

**File Highlights:**
- lib/i18n/config.ts: i18next configuration
- hooks/useFormatting.ts: Formatting utilities with locale support
- lib/utils/unitConversion.ts: Unit conversion logic
- components/settings/*Selector.tsx: Language and measurement selectors
- locales/*/: Translation files for 5 languages

eb609e1260 fix(mui): Migrate from Grid to Grid2 API (MUI v7)
Issue: MUI v7 deprecated the old Grid API with 'item', 'xs', 'sm', 'md' props.
Warnings: 'The item prop has been removed', 'The xs/sm/md props have been removed'

Solution: Migrate to Grid2 component with new 'size' prop:
- Changed Grid import to Grid2 (aliased as Grid)
- Removed 'item' prop from all Grid components
- Changed xs={6} sm={4} md={2} to size={{ xs: 6, sm: 4, md: 2 }}

Reference: https://mui.com/material-ui/migration/upgrade-to-grid-v2/

All Grid warnings now resolved.

1044f228f2 fix(ui): Fix homepage grid layout spacing and alignment
Issue: After MUI v7 upgrade, Quick Actions and Today's Summary
cards were not evenly sized - they were content-sized instead.

Solution:
- Quick Actions: Added height: '100%' and flexbox layout to ensure
  all cards are the same height within each row
- Today's Summary stats: Added minHeight: '120px' with flexbox to
  ensure consistent card heights

Result: Both sections now have evenly spaced, consistent layouts
regardless of content length.

79966a6a6d Add voice intent classification for hands-free tracking
Some checks failed
CI/CD Pipeline / Lint and Test (push) Has been cancelled
CI/CD Pipeline / E2E Tests (push) Has been cancelled
CI/CD Pipeline / Build Application (push) Has been cancelled
Implemented comprehensive voice command understanding system:

**Intent Classification:**
- Feeding intent (bottle, breastfeeding, solid food)
- Sleep intent (naps, nighttime sleep)
- Diaper intent (wet, dirty, both, dry)
- Unknown intent handling

**Entity Extraction:**
- Amounts with units (ml, oz, tbsp): "120 ml", "4 ounces"
- Durations in minutes: "15 minutes", "for 20 mins"
- Time expressions: "at 3:30 pm", "30 minutes ago", "just now"
- Breast feeding side: "left", "right", "both"
- Diaper types: "wet", "dirty", "both"
- Sleep types: "nap", "night"

**Structured Data Output:**
- FeedingData: type, amount, unit, duration, side, timestamps
- SleepData: type, duration, start/end times
- DiaperData: type, timestamp
- Ready for direct activity creation

**Pattern Matching:**
- 15+ feeding patterns (bottle, breast, solid)
- 8+ sleep patterns (nap, sleep, woke up)
- 8+ diaper patterns (wet, dirty, bowel movement)
- Robust keyword detection with variations

**Confidence Scoring:**
- High: >= 0.8 (strong match)
- Medium: 0.5-0.79 (probable match)
- Low: < 0.5 (uncertain)
- Minimum threshold: 0.3 for validation

**API Endpoint:**
- POST /api/voice/transcribe - Classify text or audio
- GET /api/voice/transcribe - Get supported commands
- JSON response with intent, confidence, entities, structured data
- Audio transcription placeholder (Whisper integration ready)

**Implementation Files:**
- lib/voice/intentClassifier.ts - Core classification (600+ lines)
- app/api/voice/transcribe/route.ts - API endpoint
- scripts/test-voice-intent.mjs - Test suite (25 tests)
- lib/voice/README.md - Complete documentation

**Test Coverage:** 25 tests, 100% pass rate
 Bottle feeding (3 tests)
 Breastfeeding (3 tests)
 Solid food (2 tests)
 Sleep tracking (6 tests)
 Diaper changes (7 tests)
 Edge cases (4 tests)

**Example Commands:**
- "Fed baby 120 ml" → bottle, 120ml
- "Nursed on left breast for 15 minutes" → breast_left, 15min
- "Changed wet and dirty diaper" → both
- "Napped for 45 minutes" → nap, 45min

System converts natural language to structured tracking data with
high accuracy for common parenting voice commands.

f640e091ce Add prompt injection protection for AI endpoints
Some checks failed
CI/CD Pipeline / Build Application (push) Has been cancelled
CI/CD Pipeline / Lint and Test (push) Has been cancelled
CI/CD Pipeline / E2E Tests (push) Has been cancelled
Implemented comprehensive security against prompt injection attacks:

**Detection Patterns:**
- System prompt manipulation (ignore/disregard/forget instructions)
- Role manipulation (pretend to be, act as)
- Data exfiltration (show system prompt, list users)
- Command injection (execute code, run command)
- Jailbreak attempts (DAN mode, developer mode, admin mode)

**Input Validation:**
- Maximum length: 2,000 characters
- Maximum line length: 500 characters
- Maximum repeated characters: 20 consecutive
- Special character ratio limit: 30%
- HTML/JavaScript injection blocking

**Sanitization:**
- HTML tag removal
- Zero-width character stripping
- Control character removal
- Whitespace normalization

**Rate Limiting:**
- 5 suspicious attempts per minute per user
- Automatic clearing on successful validation
- Per-user tracking with session storage

**Context Awareness:**
- Parenting keyword validation
- Domain-appropriate scope checking
- Lenient validation for short prompts

**Implementation:**
- lib/security/promptSecurity.ts - Core validation logic
- app/api/ai/chat/route.ts - Integrated validation
- scripts/test-prompt-injection.mjs - 19 test cases (all passing)
- lib/security/README.md - Documentation

**Test Coverage:**
 Valid parenting questions (2 tests)
 System manipulation attempts (4 tests)
 Role manipulation (1 test)
 Data exfiltration (3 tests)
 Command injection (2 tests)
 Jailbreak techniques (2 tests)
 Length attacks (2 tests)
 Character encoding attacks (2 tests)
 Edge cases (1 test)

All suspicious attempts are logged with user ID, reason, risk level,
and timestamp for security monitoring.

8e3567e3d6 Add rate limiting to API endpoints
Some checks failed
CI/CD Pipeline / Lint and Test (push) Has been cancelled
CI/CD Pipeline / E2E Tests (push) Has been cancelled
CI/CD Pipeline / Build Application (push) Has been cancelled
Implemented comprehensive rate limiting for API security:

- Created custom Next.js-native rate limiter using in-memory store
- Added 5 rate limit configurations:
  - authLimiter: 5 requests/15min for login/register/password-reset
  - aiLimiter: 10 requests/hour for AI assistant queries
  - trackingLimiter: 30 requests/min for activity tracking
  - readLimiter: 100 requests/min for read-only endpoints
  - sensitiveLimiter: 3 requests/hour for sensitive operations

- Applied rate limiting to endpoints:
  - /api/auth/login, /api/auth/register, /api/auth/password-reset
  - /api/ai/chat
  - /api/tracking/feeding (GET and POST)

- Rate limit responses include standard headers:
  - RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset
  - Retry-After header with seconds until reset

- Tested with 7 sequential requests - first 5 passed, last 2 blocked with 429

Note: Current implementation uses in-memory store. For production with
multiple instances, migrate to Redis-backed storage for distributed
rate limiting.
