1. Client discovers OAuth endpoints via .well-known
2. Client optionally registers via /register
3. Client redirects user to /authorize with PKCE challenge
4. User enters API key and submits
5. Server redirects back with authorization code
6. Client exchanges code + verifier for access token
7. Client uses access token as Bearer token for API calls
