 - **Connection management** — multi-session: hold several DBs open in one browser and switch from a topbar dropdown. Saved connection presets in `localStorage` with optional password (eye-icon reveal, closed by default). Passwords are kept in process memory only on the server.
 - **Standalone tools** — `/generate`, `/enrich`, `/export` mirror the CLI commands as forms.
