Know what can break before it breaks.
This audit maps each external dependency to the surfaces that rely on it, assigns a criticality tier, proposes a fallback plan, and runs a lightweight browser reachability probe.
Opaque cross-origin fetches count as reachable if the browser can complete the request.
