In user-key mode a browser with no stored Ollama key now gets a polished
gate instead of the app shell: one masked input with a show/hide toggle,
a single Continue button, inline validation errors, and a "?" help sheet
with the steps to a free key.
- Validates the draft key through /api/health (real 1-token probe) before
saving; invalid-key and network failures read differently.
- Key still lives only in this browser's localStorage; nothing server-side.
- Gate wraps /, /create and deck study; server-key and local-daemon modes
skip it; removing the key in Settings brings it back.
- Removes the now-redundant dashboard/create API-key banner.
- Monochrome corner glows (dark near-black / light near-white), 24px card,
48px field and button, gentle fade/slide-in, reduced-motion aware.
- Help modal: centred dialog on desktop, bottom sheet on mobile, closes via
X, Escape or backdrop.
- README and browser suites updated (34 gate checks, 15 key-flow checks,
12 shipped-default checks; ui/folders/docs/pwa/security/contrast green).
