+### 2026-06-03 — frontend v2.8.74 — Mini App chat alignment fix + read-only email field
+
+- **Chat both-sides bug:** in the Mini App chat every bubble rendered on the
+  same side in one colour. Root cause: `isMine = senderId === selfId` — when
+  `selfId` was undefined it matched system/welcome messages (no senderId), so
+  all bubbles looked "mine". Fixed: ids normalised (string | populated object),
+  a match now requires BOTH ids non-empty, and `selfId` falls back from `_id`
+  to `id`. Own = right/primary green, support/system = left/neutral grey.
+  (telegram-chat-bubble.tsx + selfId hardening in telegram-mini-app-view.tsx.)
+- **Read-only email:** the email field is now disabled by default with an
+  explicit «تغییر ایمیل» toggle, in BOTH the Mini App settings and the web
+  account-general form. Together with the backend pending-email flow (v2.8.68),
+  email can only change after the code sent to the NEW address is verified —
+  no silent change by typing + save.
+**Verification:** tsc + eslint clean.
