Audit an agent card.

Drop in any domain. We GET /.well-known/agent-card.json, render the anatomy, and run a ten-point A2A discovery checklist. Default URL is immersivecommons.com — the most fleshed-out public card we found in the wild as of May 2026. Pass ?url=<your-domain> in the address bar to preload another.
