/* Forecast Eagle — highway signage design system
 *
 * Shares weather.city's visual language so the two sites read as one network:
 * MUTCD guide-sign green, motorist-services blue, warm paper ground, and Overpass
 * (the open metric-compatible cut of FHWA Highway Gothic — the actual Interstate
 * signage face). Tokens below are weather.city's, unchanged, on purpose.
 *
 * Forecast Eagle's own note within that system is the Interstate route shield,
 * which is already red/white/blue — so the highway motif and the federal/American
 * identity are a single mark instead of two competing ones.
 *
 * The page is light paper throughout. Model imagery sits in a dark inset panel,
 * the same way weather.city frames its national outlook figures: reflectivity and
 * satellite fields need a dark ground, the surrounding document does not.
