/* ============================================================================
   StratoSig — public marketing surface
   ----------------------------------------------------------------------------
   Design fingerprint (jarvis-core/config/estate_design_registry.json):
     layout    meteorological chart — isobar field, signal cards as stations
     type      Zilla Slab display / DM Sans body / IBM Plex Mono data
     palette   cool slate paper + graphite ink + oxide orange, ice hairlines
     motion    scroll-driven isobar draw-in; hover only elsewhere
     density   6

   This stylesheet REPLACES /static/style.css on public pages. The signed-in
   app shell stays dark and keeps style.css — do not merge the two.
   Legacy token names (--border, --text-primary, …) are re-pointed to light
   values at the bottom of the token block so a page's own inline <style> that
   still references them renders correctly instead of half-dark.
