**Palace Mail self-heal complete — all clear.**

Here's what was tested:

**Layout:** Page renders correctly at `/mail` with owner tabs (Junwon/Ace), account domain pills, split email-list/detail layout, compose button, and email rows with sender/subject/date.

**APIs tested — all passing:**
- Inbox for all 6 accounts (junwon-manglasabang, junwon-palace, junwon-palacering, ace-manglasabang, ace-palace, ace-palacering)
- Sent folder for all accounts
- Message detail (uid, subject, from, to, date, html/text, attachments)
- Search (returns results, empty for no match)
- Archive/Delete (correct error handling)
- Attachment download (correct content-type, 200 response)
- VAPID push key endpoint

**JavaScript structure:** All 35 `getElementById` calls reference valid IDs, all event listeners wired (compose, reply, forward, send, search, load-more, thread-toggle), all fetch URLs correct, account IDs match backend exactly.

**No bugs found. No fixes needed.**
