  <h1>HVAC agents — no Control Center here</h1>
  <p>The Next.js UI is deployed on <strong>Vercel</strong>. This Space is not the product frontend.</p>
  <p>Backend + O1–O20 agents: <a href="https://huggingface.co/subhan07/hvac-agents">huggingface.co/subhan07/hvac-agents</a></p>
  <p>To run the API on Hugging Face you need a Docker Space (PRO). Until then run <code>uvicorn backend.main:app --port 8000</code> locally and point Vercel <code>HVAC_API_ORIGIN</code> at that host.</p>
