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

**What was tested:**
- Layout: owner tabs (Junwon/Ace), account domain pills, split list/detail layout, compose button, folder pills
- All 6 inbox accounts across 3 domains (manglasabang, palace.fund, palacering) — all returning emails
- Sent folder, message detail, attachment download, search
- Web push subscription endpoint

**Result:** No bugs found. No fixes needed, no rebuild performed.
