OpenRouter's Image API catalog (GET /api/v1/images/models) no longer lists
x-ai/grok-imagine-image-quality; it lists x-ai/grok-imagine-image-2.0. Swap
the curated _IMAGE_API_MODELS row, with every knob taken from the live
catalog entry: the same 14 aspect ratios, 1K/2K, n=1, 3 references, plus a
quality enum (low|medium) the old row never declared.
The direct xAI backend keeps grok-imagine-image-quality: xAI's authed
/v1/image-generation-models still serves it.
