      This software displays system performance characteristics in real-time
      on Framework 16 laptop LED Matrix Panels, including CPU utilization,
      battery status, memory usage, disk I/O, network traffic, temperatures,
      and fan speeds. Includes robustness improvements for permission handling
      and graceful degradation when hardware is not available.
