Inspect and debug live web pages using the Chrome DevTools Protocol via the `bdg` CLI. Use for targeted DOM queries, computed style checks, layout debugging, and CDP method calls without loading a full page snapshot. Prefer over chrome-devtools-mcp for token efficiency. Trigger on: "inspect element", "check computed styles", "query the DOM", "what does the DOM look like", "debug layout", "check the CSS on", "run a DevTools query", "what's the rendered style of", "inspect the page".
