/* ============================================================================
   VibzRoom — Pro UI theme & layout.
   DaisyUI provides the components; here we (1) retune the dark/light themes to a
   professional indigo-on-slate palette, and (2) build the meeting-app shell:
   app bars, a Zoom-like bottom control dock, glass panels & bottom sheets, and
   the canvas/stage/joystick — all responsive.
