/* Design notes (2026-07 redesign):
   - Warm paper palette, serif (Newsreader) for headings and the wordmark,
     system stack for everything else. One webfont, non-italic subset only.
   - Single column, max 680px. Cards on a soft background.
   - Plain language on the surface; scoring machinery behind disclosures.
   - Theme: follows system preference until the user toggles; the choice
     persists in localStorage. body[data-th] carries the active theme.
   - Every wait state is designed: cold start (~60s after idle) gets staged
     messages; first guide generation (~10-20s) narrates what's happening.
   - No layout shift: the status line has fixed height, skeletons match
     final card geometry. prefers-reduced-motion disables all animation. */
