Characterize the bestfits/ entries before moving their mapping out of
OpenNest.IO: golden bytes for hand-built sets, field-by-field restore of
hand-built and computed sets (kept results and used plate sizes only), a
nest without saved best fits, and the loaded-candidate frame on a rotated
source drawing, which today rebuilds to a different pair than its saved
bounds.
