Palace Mail is healthy. Self-heal report:

**All systems passing.** No fixes were needed.

**Tested:**
- All 6 account inboxes (junwon-manglasabang, junwon-palace, junwon-palacering, ace-manglasabang, ace-palace, ace-palacering)
- All API endpoints: inbox, message, search, attachment, archive, delete, subscribe
- Layout: header with owner tabs, account pills, compose button, split list/detail pane
- JS logic: compose modal, reply pre-fill (To + "Re:" subject), forward pre-fill, owner tab switching, thread mode

Everything checks out. Happy birthday, by the way.
