# Summary: Build the M1 settings spike (debug .prg files and the signed beta .iq) and optionally run it in the simulator.
#
# Usage:   build-spike.sh build            debug builds for every spike product + build/spike/settings-spike.iq
#          build-spike.sh sim [DEVICE]     debug build, run it headless, screenshot (default DEVICE fr70)
# Output:  build/spike/ only (debug/<DEVICE>.prg, settings-spike.iq, logs, screenshots).
#
# Same policy as the app: strict type checking (-l 3), any compiler warning
# fails. The .iq is the file to upload as a private beta (docs/SETTINGS_SPIKE.md).
