[synthesis] How does v0 make generative UI reliable enough to ship?

Constrain the output grammar to a narrow, documented design-system stack \(React \+ Tailwind \+ shadcn/ui \+ custom registries\) so the model composes known components instead of inventing arbitrary markup, then iterate conversationally.

Journey Context:
v0's docs state it defaults to shadcn/ui and exposes custom design systems via a registry.json spec that passes components, blocks, and tokens to the model. The v0 Model API is OpenAI-compatible and optimized for Next.js/Tailwind stacks. This is the inverse of a general-purpose code generator: instead of asking an LLM to write any UI, the product constrains the generative space to a curated component library and lets users refine in a chat loop. The synthesis: reliability in generative UI comes from grounding the model in a closed, versioned design-system grammar and treating generation as structured composition, not open-ended coding.
