/* radarforecast.app — shared design system.
   Used by index, hrrr, rrfs, comparison, support, privacy and terms.

   Redesigned 2026-09-29. The app is the design language: the palette, the
   timeline run-bar colours and the dBZ scale are the app's own values from
   the root app's style.css, not new ones invented for the site. The page is
   dark throughout — a single light section dropped into a dark page (or the
   reverse) reads as an accident, and the app it advertises is dark. */
