/* ============================================================
   AX-UI — Shared "Apex" Design Layer
   ------------------------------------------------------------
   A small, opt-in set of reusable component classes built
   entirely on the existing design tokens defined in main.css
   (:root variables: --primary, --primary-light, --bg-light,
   --bg-white, --text-dark, --text-medium, --text-muted,
   --border, --border-light, --success/--warning/--error,
   and the --green-* scale).

   Goal: a calm, spacious, editorial aesthetic that can be
   adopted screen-by-screen. Every class is prefixed `ax-`
   so it is strictly opt-in and never leaks into existing
   platform markup. Keep the platform font
   ('Plus Jakarta Sans') — do NOT import a new one.

   First adopter: the Knowledge Base admin screen.
