Optional `backgroundMode` is `complex` (semantic foreground segmentation; default) or `flat` (solid-colour background removal). Prefer `flat` when the background is known to be solid. Only `flat` accepts optional `screenColor`: `auto`, `#RRGGBB`, or omitted for automatic detection by the service. Do not select a colour on behalf of `auto`. The client requires the signed-in account, owns canvas/folder context and task identity, and returns only bounded queue state.
 7. Preserve existing relative paths when a small edit is sufficient so client resource identities remain stable.
 8. Do not edit `.agent/manifest.json`, revision counters, version records, resource IDs, canvas identities, source provenance, generation ledgers, or browser receipts by hand.
 9. Do not create a version when no game file changed. The client compares content fingerprints and advances revision only after an actual source change.
