Validate text-to-video routes against the model default.
The parser validates each primary binding against dflt.resolution and dflt.audio, but it retains text-to-video bindings without that check. A snapshot can therefore admit a hosted route that cannot serve or price an omitted-input default request.
Apply the same positive-rate check before assigning card.text_to_video[provider].

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Enforce the Recraft size envelope before submission.
The generic 14142-pixel limit permits 4096x4096 for fal-ai/recraft/v4.1/text-to-image. The catalogue limits this model to a 2048-pixel maximum edge. This mismatch allows an out-of-envelope paid request to reach fal.
Add a Recraft-specific maximum-edge check.

GG image/video execution and client eligibility assumed a Vercel binding, so catalogue updates alone could not expose models such as Gemini Omni 1.1 or restore hosted Seedance. This addresses the shared routing contract: the service catalogue now declares a hosted operation independently of BYOK provider bindings, with fal as the default for supported image and text-to-video models.
Related to #1019; follows the catalogue refresh in #1020.

GG_FAL_KEYandGG_FAL_ADMIN_KEYfor the same fal billing account/team. The admin preflight verifies access, not shared account ownership.test/desktop-media-hosted-fal-compatibility.md.Hosted fal generation/download is bounded to 240 seconds with a further bounded 20-second receipt wait. Missing receipts and work that outlives the process require reconciliation; durable asynchronous recovery remains separate work. Hosted references/image-to-video and broader media-family migrations remain outside this change. The catalogue is curated: switching providers does not automatically list newly released models.
