/* GovHub 2.0 — public marketing landing page (`/`, landing.html).

   A self-contained LAYER on top of app.css: it reuses the app tokens (brand
   blues, neutrals, status colors, spacing, radii, easing) so the marketing
   surface and the product share one visual identity, and adds only what the
   app deliberately lacks — display type sizes, hero gradients and motion.

   Scope: every rule is namespaced `.mk-*` and only landing.html loads this
   file, so nothing here can leak into the app shell.

   RULE: colors live ONLY in the :root block below (component rules use
   var(--…)); spacing uses the app's --space-* scale. Component-intrinsic
   sizes of the drawn product shots (orb diameters, mini font sizes) stay
   local to their rule.

   Motion honours `prefers-reduced-motion` (app.css already collapses
   durations globally; the reveal fallback below keeps content visible). */
