# The Space runs the firmware's own inference engine -- the same C code the
# ESP32 compiles, built statically and shipped as a binary. A Python
# re-implementation would be easier to write and would prove nothing: what
# matters is how the C engine behaves after quantization, because that is what
# runs on the board.
#
# The binary is here rather than the sources because this is a release
# artefact, exactly like the .bin files in the firmware repository.
