/* ==========================================================================
   Broadlink2MQTT — design system

   Two accents, used with intent, never decoratively:
     --ir   infrared red   the device side of the bridge
     --ha   HA blue        the Home Assistant side
   A red-to-blue gradient means a signal is being converted between them.

   Geometry echoes the RM4 mini: a rounded square, generous 20-24px radii.
   Dark only, deliberately — the hardware is matte black and the IR glow
   only reads against it.
