/* ==========================================================================
   Territory Business Continuity Dashboard — design tokens
   Visual direction: a telecom NOC / storm-radar console. Deep navy field,
   a teal radar sweep for "calm scanning", and an amber-to-red signal scale
   for rising risk — the same ramp used in the app icon's storm-bolt mark.
   No external font/network dependency: system font stack only, so the
   installed app is 100% functional offline from first paint.
