## UI routes

| Route | Purpose |
|-------|---------|
| `/login` | Yimaru-style login — test-user dropdown + locale switcher |
| `/profile` | Own profile — avatar, org, role switch, sign out |

## Clinical withhold notes

Auth endpoints do not expose clinical data. Role list / `active_role` on session determines withhold behavior on downstream endpoints.
