/* ============================================================================
   Comeback — the website.

   Show the app, don't describe it. Every section is one phone and one short
   sentence; an earlier version was paragraphs of prose and read like a document.

   The phones are real interface, rebuilt in HTML with the app's own tokens from
   mobile/src/theme/tokens.ts — not screenshots, so they stay sharp at any size and
   adapt to light and dark like the app does.

   No fonts, no scripts, no third-party requests. That's partly speed and partly
   the point: a health app's site that phones home to five ad networks has already
   lost the argument.
