name: Fetch Firmware

# The firmware is built by the upstream repository
# (mnh-jansson/open-battery-information) and attached to its GitHub
# releases. This workflow simply downloads the latest binaries and commits
# them here, so the uploader always serves the newest firmware without
# needing a local PlatformIO toolchain.
