   Life Ahead — the public landing page.

   The iOS app's look on the web: Archivo, the app palette, rounded cards, one
   red accent. Values come from design_handoff_landing_page/ (tokens.css and
   landing-reference.html) and are exact on purpose; do not round them.

   Theme resolution, same convention as app.css:
     :root / html[data-theme=light]        light
     html[data-theme=dark]                 dark, chosen with the toggle
     prefers-color-scheme + :not([light])  dark, following the system

   Self-contained: no framework, no build step, no CDN.
