Review feedback on #422. - showDisplaySaveResult tested `xhr.status >= 400` for failure, so a network error — which reports status 0 — was waved through as "Display settings saved". That's the same class of false-success bug this branch set out to fix. Test the 2xx range instead, and let a response body refine a successful verdict without overturning a failed one. - Annotate the _copies_fits_hardware helper, matching the annotated helpers already in api_v3.py. - Cover the vertical divisibility branch: chain_length 2 would divide evenly, so only parallel 3 can produce the rejection, which pins the branch to the right hardware dimension.
