Add an image-only batch mode to /generate: select up to 100 PNG/JPEG/WebP images (5 MiB each), review the list, and create one independent generation per image. Progress counts server-confirmed admissions, with a private result link for every accepted image.

The batch keeps original files and per-image UUIDs in IndexedDB. It sends one POST at a time up to the existing server admission limits; it does not wait for earlier character reviews. Queue-full responses back off with the same UUID, while uncertain outcomes pause the batch. Closing the page preserves the remaining work for explicit resume.

Safety and recovery:

• Web Locks prevent concurrent senders; transactional snapshot checks reject stale start, resume, and delete actions.
• Receipts, input deletion, and pending history delivery commit together. Interrupted history updates resume without another generation request or extending result expiry.
• Expired inputs cannot erase still-live result links. Saved results remain readable when new image generation is disabled.
• Switching modes preserves the single-generation draft and recovery UUID. A pause before HTTP restores the prior attempt deadline.

No public HTTP contract, worker, YDB schema, quota, or budget changes.

Validation:

• Full test suite: 3,486 passed, 4 skipped; typecheck, lint, mock production build, and diff checks passed.
• Real local browser with IndexedDB/Web Locks and synthetic API: 100 independent admissions, cross-tab stale-start/deletion checks, all result links, and read-only/empty-mode transitions.
• Desktop/mobile viewport checks in both themes. Physical Android hardware and a maximum-size 500 MiB batch stress test were not available.

No production deployment or paid generation runs were performed.

Confidence Score: 5/5

The PR appears safe to merge; all three previous findings are addressed and no new actionable issue was found.

Summary

Adds a resumable, image-only batch mode to /generate.

• The generate page lets people prepare an image batch beside the single-pet form.
• Each image in a batch gets its own request and progress.
• Accepted batch images keep their private result links and history.

This review inspected the code and tests; it did not run the test suite.
