/* Outclass marketing pages — static tenant CSS.
   Brand tokens ported from client/src/pages/public/OutclassLanding.css (the live React landing
   page). This file styles pre-rendered HTML served directly by tenants/outclass/routes.json, so
   it deliberately skips the framer-motion scroll demos — those need a JS bundle no crawler runs
   anyway (see 2026-08-11 GEO audit). Reveal animation here is CSS-only, gated behind
   prefers-reduced-motion, and every element is visible with no JS at all. */

   .oc-button--light is declared ABOVE .oc-button--header at equal specificity (0,1,0), so on
   an element carrying both, --header's `background: transparent` wins on source order and the
   white fill silently does nothing. Codex caught exactly that on #2180: the class was on all
   six hand-authored pages and every one of them still rendered the old outline. This combined
   selector is (0,2,0), so it wins regardless of where either single-class rule sits. Do not
   "simplify" it back to reordering: --light is also used on body CTAs on these pages, and
   moving it would drag those through the header rule's ordering too. */
