 ### LED Status / Error Patterns
 The firmware uses a small set of LED patterns to indicate status and blocking errors. When `LED_DEBUG_ENABLE` is disabled and `LED_EXTERNAL_AS_DEBUG` is enabled the external IR LED mirrors ONLY error patterns (0%/50% duty). Non‑error patterns are not mirrored.
 
-| State | Category | Repeat | Pattern (ON/OFF ms) | Meaning |
+| State | Visual | Category | Repeat | Timing Pattern (ms) | Meaning |

 Guidelines for adding new patterns:
 - Keep error patterns short, distinctive, and repeating.
 - Reserve long holds (>600ms ON) for critical failures.
 - Use non-repeating patterns to acknowledge one-shot events (e.g. successful connection).
 
-Potential future additions (not implemented yet):
-- StorageError: two long ON pulses (e.g. NVS/flash failure).
-- ConfigError: triple short pulses repeating (invalid configuration / preferences corrupt).
-- ThermalWarning: slow ramp or alternating duty (would require PWM pattern support).
-- FirmwareUpdate: progressive heartbeat (increasing ON time) while updating OTA.

 - UVC doesn’t appear on the host?
   - Switch mode to UVC via CLI tool, replug USB and wait 20s.
