[cost\_intel] Synchronous UI component generation with <500ms latency budget

Use Claude 3.5 Sonnet or GPT-4o with few-shot prompting; exclude o1/o3 due to 3-8s time-to-first-token latency cliff and tendency toward over-abstraction

Journey Context:
Reasoning models take 3-8 seconds to begin outputting tokens due to internal chain-of-thought, violating the 100-500ms RAIL model budget for perceived immediacy. Additionally, o1 generates 'enterprise architecture' patterns \(unnecessary factory abstractions\) for simple components, lowering user acceptance rates to 60% vs 90% for 4o on single-file components. The 10x cost premium compounds the latency issue.
