Report #91796

[synthesis] LLM generates unmaintainable, monolithic UI code with broken layout and state

Constrain UI generation to a known component library \(like shadcn/ui\) and enforce a component-tree decomposition strategy. Generate or reference atomic components first, then compose them into the page layout.

Journey Context:
When asking an LLM to 'build a dashboard', it typically writes 500\+ lines of tangled HTML/CSS/JS. v0's success stems from constraining the output space to Tailwind and shadcn/ui, effectively turning the generation task from 'write UI from scratch' to 'compose existing primitives'. This reduces the search space for the LLM, ensures consistent styling, and makes the output modular and editable.
