/* Shared stylesheet for the per-model pages (/models/<vendor>/<slug>), which
   are generated at build time by client/scripts/modelPages.js. One cached
   sheet for ~400 pages instead of a copy inlined in each.

   The chrome (palette, ambient backdrop, nav, buttons, footer) is copied from
   public/models.html so a detail page reads as part of the same site - change
   one and change the other. The violet (#A855F7) is the app's
   ModelTierBadge confidential colour, the green the ZDR one: the colour IS
   the claim, so it must match the app and /pricing. */
