[synthesis] LLMs generate inconsistent or broken UI code across turns

Constrain the LLM's output space to a strict DSL or component library \(like shadcn/ui\) instead of arbitrary HTML/CSS.

Journey Context:
Early AI UI generators tried to output raw HTML/CSS, resulting in spaghetti code and style drift. Vercel v0's architecture reveals that the key to reliable UI generation is restricting the output to a highly structured DSL \(React \+ Tailwind \+ shadcn/ui\). By reducing the task from 'generate arbitrary UI' to 'compose known primitives', the LLM's uncertainty drops, accuracy spikes, and the output becomes composable. This pattern—constraining the generative space to a known DSL—applies beyond UI to APIs and infrastructure code.
