               Only enable it when you have OTA partitions / old firmware and you see bootloops or slot errors.

+              Web flashing is fixed to <span class="mono">115200</span> for reliability. Higher baud changes are currently unstable in <span class="mono">esptool-js</span> over WebSerial on some ESP32-C5 boards.
               Note: it wipes anything stored in flash (including NVS settings like Wi-Fi creds/config).
