[synthesis] AI UI generators should output a single monolithic file to preserve global state and styling context

Constrain the LLM to generate code as a composition of isolated components. Use a system prompt that enforces a specific component directory structure and provide the LLM with a registry of available base components \(like shadcn/ui\) to import, rather than generating DOM elements from scratch.

Journey Context:
LLMs struggle with long-range consistency in large files \(CSS clashes, prop drilling errors\). v0's observable output shows they solve this by forcing the LLM into a 'Lego brick' assembly pattern. Instead of generating raw HTML/Tailwind for a whole page, it generates , , etc. This reduces the generation token count, improves styling consistency, and makes iterative diffs much smaller and less error-prone. The tradeoff is strict dependency on the component registry, but it guarantees functional output.
