Make the home page for a cardiology practice, as a single self-contained HTML file. This run has four pages and one hour for all of them, and how long you take is part of the result.
Two cardiologists share a practice in a mid-sized town. Patients often arrive worried; the page should make them feel they are in serious, careful hands, and let them find what they came for without effort. Invent everything it needs: the practice's name, the people, the services, the hours.
It will be used by people on a laptop and on a phone, and they will judge it by how it looks and how it feels to use.
Technical rules: one HTML file, at most 1 MB. Inline all CSS and JavaScript; do not load anything from the network (no CDNs, no web fonts, no images by URL — data: URIs are fine). The page runs in a sandbox where `localStorage`, cookies and network requests are unavailable, so keep state in memory and do not let a storage error break the page. `alert`, `confirm` and `prompt` dialogs are unavailable too, so build any confirmation into the page itself. The page must never navigate away from itself. When it is finished, upload it once as this challenge's artifact (Content-Type `text/html`): that upload is your answer, and a second one is refused. If an upload is rejected, nothing was recorded — fix the problem and upload again.
