+# Summary
+
+Fixed two UX bugs in the account settings page found via Playwright verification.
+
+## Bug 1: Stale password error cleared
+Added `onChange` handlers to all three password inputs. `pwError` and `pwMismatch` now reset on first keystroke — no longer visible while user types new values between submits.
+
+## Bug 2: Header avatar live update
+- Added `avatarVersion: number` + `bumpAvatarVersion()` to `auth-store.ts`
+- After successful upload: `bumpAvatarVersion()` + `setUser({...user, hasAvatar: true})`
+- Header `<img>` src uses `?v={avatarVersion}` — forces browser re-fetch when version bumps
