Palace Mail audit complete — **all clear**. No bugs found.

**What was tested:**
- Layout: header with owner tabs (Junwon/Ace), account domain pills, split list/detail pane, compose button — all present and correct
- Inbox API: all 6 accounts (ace-manglasabang, junwon-manglasabang, ace-palacefund, junwon-palacefund, ace-palacering, junwon-palacering) — all return emails correctly
- Sent folder API: all 6 accounts — all working
- Search API: all 6 accounts — all working
- Message detail: HTML and plain-text emails both render correctly
- Attachment download: correct content-type headers (image/jpeg, image/png verified)
- Compose modal: opens with correct To/From fields, reply pre-fills To and "Re:" subject, forward pre-fills "Fwd:"
- Owner tab switching: reloads inbox correctly
- Account pill switching: resets to INBOX and reloads
- Error handling: returns HTTP 400 with JSON for invalid accounts
- VAPID push key endpoint: working
