type authentication_error status 401
What happened
The `Authorization` header was missing, malformed, or carried a key Clement doesn't recognize. Browser callers may have lost their session cookie (logged out, cleared cookies, or visited the wrong subdomain).
How to recover
Set `Authorization: Bearer cl_live_…`. If the key was revoked, see `api_key_revoked` and rotate.
