Drag-and-drop uploads that record the generator (v0.15.0) · Sprite Manager devlog

Generated images come back through an upload zone on each request: drag them in, paste them, or pick files, several at once. The same zone on an entry in review adds more options.
Every upload says which image generator made it, and the delivered sprite's provenance note records it.
Each upload is checked (a real PNG, JPEG or WebP, and not a repeat of one already there) and kept exactly as it arrived. The background is removed on a copy.
After an upload the page stays on that request, with a "✓ uploaded" bar and the new images outlined, instead of jumping around. Accepting or rejecting keeps your place too.
Uploads that arrive at the same moment can't overwrite or lose each other. 82 automated tests.
