/* =============================================================================
   enactive.dev — landing page
   Brand v1.0. Colour, type and geometry come from /brand/brand.css; the tokens
   below are the subset this page needs, copied verbatim. Change one, change both.

   This page deliberately commits to the dark theme: Enactive is a dark desktop
   environment, and the site should look like the product, not like a document.
   Every colour is therefore painted explicitly — nothing is inherited.
