Palace Mail health check complete. All features pass:

**Layout**: Header, owner tabs (Junwon/Ace), account pills, split list/detail view, compose button — all rendering correctly.

**APIs tested**:
- Inbox fetch across all 6 accounts (ace/junwon × manglasabang/palace.fund/palacering) ✓
- Message detail + attachment download ✓
- Search ✓
- Archive + delete endpoints ✓
- Push notifications (VAPID key + subscribe) ✓

**UI interactions**: Compose modal opens with all fields (To, Subject, Body, From dropdown with 6 accounts). Email click shows detail panel.

**No bugs found, no fixes needed.**

One note: there's an email in the inbox (uid=447) from Junwon with a screenshot and "bottom. wrong. fix." — that screenshot shows **Palace Code**, not Palace Mail. If that's a bug report, it's for `/code`, not `/mail`.
