Palace Mail is fully healthy. Here's the summary:

**All features passed:**
- Layout renders correctly — header tabs, account pills, split pane, compose button
- All 7 API endpoints working (`/inbox`, `/message`, `/search`, `/archive`, `/delete`, `/attachment`, `/vapid-key`)
- All 6 accounts connect via IMAP (junwon + ace across manglasabang/palace.fund/palacering)
- Email detail, reply pre-fill (To + "Re:" subject), forward ("Fwd:"), thread grouping, search, pagination, swipe gestures — all sound
- No console errors, no broken logic

No fixes were needed.
