/* ════════════════════════════════════════════════════════════════════════
   MiddyMind UI Kit — reusable agent-interaction UI primitives.

   Patterns mined from Omnigent's ap-web (Apache-2.0) and reimplemented
   dependency-free for the vanilla-JS SPAs. See docs/UI_IMPROVEMENTS.md.

   SINGLE SOURCE OF TRUTH. Do not edit the copies under operator/static or the
   per-demo static dirs — edit this file (middymind/app/static/ui-kit.css) and
   run `scripts/sync-ui-kit.sh` (or `make ui-kit`) to propagate to every demo.

   Token-agnostic: derives its palette from whatever the host SPA defines
   (--accent / --surface / --text … OR --panel / --fg …), with hard fallbacks,
   so it drops cleanly onto the dark app/operator shells and the light
   empowerreg/clearedai shells alike.
