Multicam Live Switch Graphics Grid

I am directing a {{broadcast_type}} with {{camera_count}} cameras and {{graphics_count}} graphics elements. Create a comprehensive director's control grid showing:
- Live camera feeds layout and camera IDs
- Graphics (lower thirds, tickers, full-screen slides) with trigger cues
- Audio inputs (mics, playback, remote feeds) with levels and routing
- Timing reference (countdown timer, segment duration)
- Talent position/movement predictions
- Backup/failsafe feeds if primary camera drops
- Color-coded by priority (must use vs. optional)
Include a legend explaining symbols and a failsafe protocol chart.
