User @davidelang mentioned @MaslowBot with the following request:...

Added a comparison of the three transport options in /home/runner/work/Maslow_4/Maslow_4/firmware/README.md: classic Bluetooth serial (SPP), Bluetooth TCP/IP/PAN-style networking, and BLE/Web Bluetooth. The conclusion is that classic serial is fine for native senders, Bluetooth TCP/IP would require an external bridge/helper outside the browser, and BLE/Web Bluetooth is the only direct browser path for the built-in UI. Addressed in 209c095.
