/* ============================================================
   livee — brand tokens, plus the components the shared Castomo system doesn't have.

   css/styles.css is the Aperture design system, cloned unchanged so the family
   stays one visual language (and so upstream fixes stay diffable). This file
   re-points that system at livee's own brand and adds livee's own components:
   the camera wall, the alert scene, the builder, the payload block, the channel
   fan-out, the FAQ and the demo form.

   Two colours carry meaning, and only two:
     --accent  livee lime (brand-kit/livee/tokens.css, --brand-2) — the brand, and
               the "live / connected / healthy" state. The mark is a live signal;
               the colour means the same thing everywhere it appears.
     --alert   amber — alert, armed, attention. Status only, never brand.
   Anything else on the page is grey.
   ============================================================ */
