Description

The admin dashboard (src/channels/admin.ts) needs a hero:theme postMessage listener so it can sync dark/light mode and CSS custom properties when embedded as an iframe inside Hero OS.

What it does

  • Listens for hero:theme messages from the Hero OS shell
  • Sets CSS custom properties (--var) on document.documentElement
  • Toggles light/dark class and data-bs-theme attribute for Bootstrap 5.3 compatibility
  • Sends hero:theme-ready signal back to parent when loaded in iframe
