/* ─────────────────────────────────────────────────────────────────
   Demo Combobulator — Shared Design System
   Inspired by AMZ-Tools (Beacon) and tr-ai-der (Confluence).
   Refined IDE chrome — one accent, one signal, monospace reserved
   for logs / kbd / tabular metadata. Nothing louder than it needs
   to be. Link this file first on every page; then layer page-specific
   rules after.
