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

**All tests passed — no fixes needed.**

- **Layout**: Header, owner tabs (Junwon/Ace), account pills (manglasabang, palace.fund, palacering), split list/detail pane, compose button — all rendering correctly
- **API endpoints**: All 6 accounts return mail, search works, message detail loads, attachment download serves correctly
- **Compose**: Opens with correct From/To pre-fill, Reply adds "Re:" prefix, Forward adds "Fwd:"
- **Account switching**: Owner tab and domain pill switching both reload inbox correctly
- **Thread grouping, swipe actions, search debounce**: All logic verified correct
- **No console errors**
