Palace Mail is fully operational — no bugs found, no fixes needed.

**All features tested and passing:**
- Layout: header tabs (Junwon/Ace), account pills (3 domains × 2 owners), split pane, compose button
- API: all 6 inboxes, sent folders, search, message detail, attachment download, archive, delete
- Compose modal: all fields present (To, Subject, Body, From dropdown)
- Reply pre-fill: correct To and "Re:" subject
- Forward pre-fill: correct "Fwd:" subject
- Owner tab switching: reloads correctly
- Account pill switching: reloads correctly

The existing non-mail errors (sharp warning, DB connection for other apps) are pre-existing and unrelated.
