"""Put the datasheet marking code on the top coat of a chip resistor STEP.

Uses the shared step2glb service's /laser-etch endpoint in flat mode: the body is
untouched and the code is added as its own floating solid group (Adom.LaserEtch)
just above the top coat. The input STEP is never modified.

usage: etch.py in.step CODE out.step jobname
prints one JSON line: service, version, job id, sha256 of input and output.
