Palace Mail is healthy. Here's the summary:

**All features tested — nothing broken.**

- Layout: Owner tabs (Junwon/Ace), account pills, split list/detail pane, compose button — all rendering correctly
- All 6 accounts confirmed working: `junwon-manglasabang`, `junwon-palace`, `junwon-palacering`, `ace-manglasabang`, `ace-palace`, `ace-palacering`
- All API endpoints pass: inbox, search, message detail, attachment, send, archive, delete, subscribe
- UI interactions: email open, compose modal, reply prefill, owner tab switching, swipe gestures, pagination — all functional
