Palace Mail is fully healthy. Here's what was tested:

**Layout** — All elements present and correct: header with Junwon/Ace tabs, account pills, split layout, compose button, detail pane.

**API Endpoints** — All 6 accounts load correctly (14 emails for ace-manglasabang, 2 for junwon-palacering, etc.), search returns results, archive/delete return `{ok:true}`, attachment download works, pagination works.

**UI Logic** — Reply pre-fills To and "Re:" subject, forward pre-fills "Fwd:", swipe gestures, thread mode, pull-to-refresh, all JS functions verified.

**Edge cases** — Invalid account returns `Unknown account`, empty search returns 400, non-existent message returns `Message not found`.

No bugs found. No fixes needed.
