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

**All systems passing:**
- All 6 accounts (3 Junwon, 3 Ace) across manglasabang/palace.fund/palacering return inboxes correctly
- All API endpoints respond correctly: inbox, sent, search, message detail, attachment download, archive, delete, push/VAPID
- Layout renders correctly: owner tabs, account pills, split pane, compose button
- Compose opens with correct From pre-selection; Reply pre-fills To + "Re:" subject; Forward pre-fills "Fwd:" subject
- Owner/account/folder switching all reload correctly
- Swipe gestures (archive/delete) and undo bar functional
- Thread grouping, shadow DOM HTML email rendering, pull-to-refresh — all working

Nothing broken. No fixes needed.
