 * 6 minut pro zdraví: the shared foundation of the public pages and the admin view.
 * The website's palette (docs/spec/brand.md, "Owner update"): page #DBE4F1, white cards, section shading #C8D3E3,
 * navy #07023A text and selected controls, flat coral #FF5670 buttons with white labels. Poppins 700 for headings
 * and buttons, Roboto for everything else, Font Awesome Free 5.15.3 icons. Spacing, radii and motion follow
 * docs/spec/design-tokens.json, so the web and the app share one design language.
