Seed eight sample files across modalities in the demo Files library and mock the list (search + pagination), details with version history, bulk delete, and thumbnails. Thumbnails are generated colour-coded SVG tiles served through the interceptable fetch path, so the grid always renders with no real file bytes. Uploads/processing stay disabled.
The demo signs in as an admin on load (no login/change-password screen; /login and /change-password bounce to the dashboard), authEnabled stays true so the People/Teams/Roles/Security settings tabs remain available, the banner notes the admin data is sample data, and the mobile editor icon is an inline SVG so it always renders.
Rewrite the demo mock API around a seeded in-memory dataset with correct response shapes so the People/Teams/Roles/Audit/Usage/API-keys tabs stop crashing (the /auth/users vs /v1/users mismatch caused users.filter() on undefined) and show realistic sample data. In-memory CRUD makes the settings buttons work. Copy edit-image.png into the demo so the mobile editor icon renders. Adds unit shape guards and an e2e admin-settings walkthrough.
