NOTE: This MIT License covers the repository as a whole **except** for the
SCServo_lib files (Feetech serial bus servo SDK), which live in
`firmware/main/boards/stackchan/` (files: SCS.{cc,h}, SCSCL.{cc,h},
SCSerial.{cc,h}, INST.h, SCServo.h) and are licensed separately under the
GNU General Public License v3.0. Their full license text is in
`firmware/main/boards/stackchan/SCServo_lib_LICENSE.txt`.

Because the firmware binary statically links the SCServo_lib code, the
combined firmware build is effectively distributed under GPL-3.0. The
gateway/ Python package, which runs in a separate process and communicates
with the device only over a network socket, remains under the MIT License
above.
