## KEY FEATURES & IMPLEMENTATION NOTES

### Authentication Flow
1. User selects contractor/worker → signup page
2. Creates email/password account via Supabase Auth
3. Verification email sent → verify-email page
4. Clicking email link → auth/callback → exchanges code for session
5. User profile created in DB with type metadata
6. Middleware enforces: unauthenticated → /auth/login, unverified → /auth/verify-email

### AI Integration
- **ABN Research:** Validates ABN → calls ABR API → extracts company details
- **Profile Builder:** AI generates worker bios, skills, certifications from 5 questions
- **Job Posting:** AI auto-generates job descriptions and matching algorithms

### Mobile-First Design
- Large touch targets (64px+), bottom nav sticky CTAs
- PWA support (manifest.json, service worker)
- Responsive: max-width-screen-sm (640px) containers
- Australian focus: AUD pricing, Australian English

### Security
- PKCE OAuth flow for auth
- SSR with server-side Supabase client for user context
- Admin operations isolated (email verification uses service key)
- Security headers: DENY framing, CSP, HSTS

### Database Design
- Row-Level Security (RLS) implied for multi-tenant separation
- Foreign keys with CASCADE delete for data integrity
- JSONB columns for flexible AI data storage (ai_research, ai_extracted)
- Point type for geolocation (location), text arrays for skills/trades/languages
