Design a Valentine’s Day expression tool with branching share flows.
Creation:
- User edits a short message
- Optional camera capture adds personal imagery
Sharing paths:
- Save locally
- Share to social platforms
- Send via email
Rules:
- User can switch sharing method at any time
- Partial progress must never be lost
- After any share action, the result remains accessible
Interaction logic:
- State transitions must be explicit and reversible
- Restart and re-share must always be possible
Intent:
- Test complex interaction flow correctness
- The experience must feel intentional, not fragile
