- 3 gpt-image-2 cover variations (deep / closeup / minimal) leaning into oskie's moody aquatic identity, away from the glossy app-icon first pass; keep the 1024 gen outputs, ignore the deterministic 3000² upscales. - gen-cover.mjs: --prompt/--label params, route the multipart upload through curl (undici fetch stalled here), bump timeout to 360s. - drop the accidentally-committed .ref-1024.jpg scratch file; add .gitignore for the transient ref/resp scratch + the regenerable 3000² images.
