- Settings -> Account: change your own password (current + new), session
preserved via update_session_auth_hash.
- Custom labels: per-user palette in Settings -> Labels; apply/remove from a
message's ... menu (menu stays open, checkmark = applied). Labels are unified
with tags; chip colours sync to the global TagColor. New Label model +
migration 0017; POST /a/{id}/label (session, owner-scoped, palette-validated).
- Sidebar Keep/Deleted folders are now always shown; count badge only when
non-empty. Updates the stale 'hide when empty' note in CLAUDE.md.
