   DRONEROTECH — site chrome
   Design system inherited from prototype/tokens.css + rail.css, measured off
   the live site (see _research/BASELINE.md). This is a deliberate single
   visual world: near-monochrome, dark header/hero fixed regardless of the
   viewer's OS theme, exactly matching the real site, which does not adapt to
   light/dark either. Colours are painted explicitly so the page holds on any
   host ground.
