-//   1. CDP `WebMCP` domain (https://chromedevtools.github.io/devtools-protocol/tot/WebMCP/)
-//   2. Lightpanda's own MCP server forwarding tools to an external LLM.

-// Both consumers reach into `tools()` / `findTool()` from Zig; the JS-side
-// surface (`registerTool`, `requestUserInteraction`) is the only part shipped
-// today.
