README: route table for `/`, `/login` and `/b/:slug`; what `VITE_DEMO_UI` does to a
production build and how to turn the demo accounts off; the two test commands that
were missing (`test:landing`, `audit:responsive`).
progress.md: the deploy entry, including the defect it caught — the deployed bundle
had every magic-login string eliminated, so the new landing would have promised "no
registration" and led to an empty form — and the two measurement traps that cost a
false pass (a Playwright context without `hasTouch` reports `pointer: fine`, and
`GET /deployments/{uuid}` nests the application object before the deployment status).
