notes: >-
  app.localstack.cloud returns HTTP 200 with text/html for every /.well-known/ path
  (single-page-app catch-all), so those are not real discovery documents and are not indexed.
  The docs host publishes a genuine machine-readable discovery surface: an RFC 9727 api-catalog
  that in turn points at /llms.txt, an MCP Server Card, and an Agent Skills index.
