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

**All systems passing:**
- Layout renders correctly — owner tabs (Junwon/Ace), account pills (manglasabang, palace.fund, palacering), split list/detail view, compose button
- All 6 inbox accounts return emails (27 total across accounts)
- Search working (6 results for "korea", 2 for "test")
- Message detail, attachment download, archive, delete endpoints all return 200
- Compose modal, reply prefill, thread grouping, swipe gestures all wired correctly
- Error handling correct for invalid accounts/UIDs

No fixes were needed.
