- Test credit card: type a 25-character string — check for overflow
- Submit the form with zip code empty — does it require zip?
- Submit a valid form and run $B console --errors

Replace session-cookie auth with JWT tokens. Currently using express-session + Redis store.

## Changes
1. Add \`jsonwebtoken\` package
2. New middleware \`auth/jwt-verify.ts\` replacing \`auth/session-check.ts\`
3. Login endpoint returns { accessToken, refreshToken }
4. Refresh endpoint rotates tokens
5. Migration script to invalidate existing sessions

## Files Modified
| File | Change |
|------|--------|
| auth/jwt-verify.ts | NEW: JWT verification middleware |
| auth/session-check.ts | DELETED |
| routes/login.ts | Return JWT instead of setting cookie |
| routes/refresh.ts | NEW: Token refresh endpoint |
| middleware/index.ts | Swap session-check for jwt-verify |

## Error handling
- Expired token: 401 with \`token_expired\` code
- Invalid token: 401 with \`invalid_token\` code
- Refresh with revoked token: 403

## Not in scope
- OAuth/OIDC integration
- Rate limiting on refresh endpoint

## Context
Build a user dashboard that shows account stats, recent activity, and settings.

## Implementation
1. Create a dashboard page at /dashboard

4. Add a settings panel
5. Use a clean, modern UI with cards and icons
6. Add a hero section at the top with a gradient background
