name: Build RPi image
# Yocto (kas) build of rpilinux-image for raspberrypi4-64.
#
# Runs on the dedicated host runner (label "yocto:host", Ryzen 9 box "ada").
# Everything persists in $YOCTO_HOME: extern/ (layer clones) + build/ (sstate)
# survive between runs -> incremental builds after the first.
# $YOCTO_HOME comes from the runner config (runner.envs.YOCTO_HOME =
# /home/bl/yocto-build, on the 1.8T disk); falls back to $HOME/yocto-build.
#
# First build takes hours (poky fetch + full image) -> runner.timeout >= 8h.
