# Firmware version = "<version.txt>-<git short hash>", e.g. 0.0.1-1d613b1. The first part is set by
# hand in version.txt; the hash says which commit was built (no dirty flag: the build always patches
# the cspot submodule). Reported by esp_app_get_description(), status.fw and GET /api/ota.
# CMake re-runs when version.txt or the checked-out commit changes.
