/* ==========================================================================
   AutoBridge Systems - Page Content Primitives (v1)
   ==========================================================================

   Class set for custom-kind hub pages: layout primitives, typography,
   callouts, grids, steps. All classes prefixed `abs-` so they never collide
   with the existing hero/card/subpage chrome in globals.css.

   This file is loaded by src/app/layout.tsx so every page on share-app sees
   it. Custom-kind page bodies can reference these classes and inherit
   styling from the document level. Brand evolution: edit this file, every
   page that uses the classes picks it up on next deploy without touching
   any DB rows.

   All colors / spacing / radii come from colors_and_type.v2.css tokens.
