/* ============================================================================
   ASTROSCAN SENTINEL — Mission Control Family Safety
   v2 Flagship Design System · May 2026
   ----------------------------------------------------------------------------
   Built on /static/css/design_tokens.css (must be loaded first).
   Identity: "Family safety with the precision of mission control."
   Mood: SpaceX Mission Control + Apple finesse.
   Visual contract:
     · Cyan #00d4ff = trust, presence, signal.
     · Green       = healthy state.
     · Amber       = warning (overspeed, signal loss, low battery).
     · Red         = SOS surface ONLY. No exceptions.
   Type: Orbitron (headings), Space Mono (data), Inter (body).
