/* ===========================================================================
   WeightLab — design system.
   A calm, precise daily-weight instrument. One pink/red signal accent on
   tinted neutral surfaces (OKLCH); restraint is the differentiator against a
   loud category. Numbers are the content, so every readout is tabular
   monospace; everything else is a clean humanist sans. Mobile-first,
   one-handed, glanceable. Tokens swap by data-theme. No texture, no chrome
   competing with data.
