"""
System reset view — admin-only UI page.

Renders a confirmation-heavy page that allows administrators to:
1. **Full Reset** — wipe all user data (DB + disk) for a fresh start.
2. **Reset & Re-import** — move originals to a reimport folder, wipe,
   and let the watch-folder mechanism re-ingest them.

Both options are gated behind the ``ENABLE_FACTORY_RESET`` feature flag.
