/* ═══════════════════════════════════════════════════════════════════════════
   SweepR — Hero Route Stage
   Owns everything inside #heroStage (.hero-stage). bridge-hero.js builds the
   markup; this file is the entire look of it.

   Every class is prefixed .hs-* so nothing can collide with the markup already
   in bridge.html; .hero-stage itself is the one shared selector. Colours,
   radii and easing come from :root in bridge.html — never hardcode a new
   palette here, the page has one.

   Layout: a CSS grid of four zones (you → handoff → shield → recipient) with
   a full-width readout underneath. The <canvas> sits behind the grid at
   inset:0; the glass cards are translucent on purpose so the particle flow
   glows through them instead of being hidden by them.
