Original-preserving masked smoke repair release

Publish one separate native1038×1515 monastery smoke repair in Art Atlas. The explicitly authorized binary mask copies only generated smoke RGBA;4,835 pixels change and every decoded RGBA pixel outside the mask stays exactly original. The entire chimney masonry from y351 down is original. Full composition and light/dark smoke/masonry comparisons were inspected. The yellow/pink bulb is corrected without changing building detail. The original and rejected full-image attempt remain available and unchanged.

73 tests pass,including an independent dependency-free full PNG decode that checks every native pixel against the original or donor,all8,338 prior complete metadata/approval objects,mask/provenance/diagnostic hashes,all11 protected runtime/server files and exact Atlas-only Docker addition. An initial72/73 run lacked permission to create a disposable Git test repository;the authorized normal-permission rerun passes all73. Desktop1440 and phone390 local Atlas checks verify all36 update/proposal image hashes,the original source hash,8,339 metadata/checksum/inventory records and visible localized-repair/pending-context/unapproved labels.
