// Same async shape as xAI (POST → { id, status }, GET → status/unsigned_urls),
// two differences only: creation POSTs to the collection root (no `/generations`
// suffix) and the account headers come from the registry entry.
// Response bodies are passed through verbatim.

// ponytail: generations only — OpenRouter has no edits/extensions endpoint today.
