[synthesis] Generating complex multi-file UI code without token limits or coherence loss

Use a two-stage generation pipeline: first, a planner model generates a high-level component tree and prop interface definition \(schema\); second, a generator model renders each leaf component independently, using the schema as a strict contract, allowing parallel generation and preventing cascading syntax errors.

Journey Context:
Generating a whole dashboard in one LLM call results in truncated output, inconsistent state, and hallucinated imports. A naive multi-file approach still lacks coherence. v0's architecture, inferred from its generation behavior and Vercel's AI SDK patterns, implies a schema-driven decomposition. The LLM first defines the skeleton \(what components exist, their props, their hierarchy\). Then, it generates the implementation of each component in isolation. This ensures that the parent component correctly imports and passes props to the child, even if the child's internal implementation is generated separately, drastically improving compile-ability and modularity.
