/* ==========================================================================
   Wedge Timer — wedgetimer.com
   System: "precision instrument on paper". The app is a software rendering of
   a physical classroom object, so the site is laid out like the object's own
   documentation: paper canvas, one decisive red, mono for anything that is a
   measurement.

   Every colour below is lifted from WedgeTimer/Views/Theme.swift, not invented:
     --red    WedgeColor.classic  rgb(0.847, 0.137, 0.169)
     --paper  AppBackground light rgb(0.973, 0.973, 0.965)
     --ink-d  AppBackground dark  Color(white: 0.055)
   The seven chips in .chips are the seven real WedgeColor cases.

   Motion contract: one sweep of the hero dial on load, nothing else. The dial
   sweeping IS the product; anything beyond it would be decoration. All of it
   is disabled under prefers-reduced-motion.
