/* =====================================================================
   מ־200 ל־800 — design system (tokens + components), task x7, "the line"
   The world: the way from 200 to 800 is a line, and the day is a line
   with stations. Home opens on a dark band where the estimated score is
   a sun-yellow dot on the 200–800 line; today's tasks are stations on a
   teal route; every practice round runs along a line of stations.
   White page, hairline cards, teal actions, sun yellow only for "you".
   One face: Heebo (800 for display and numbers, 400/500 for text).
   DESIGN.md at the repo root describes the system.
