Production-grade OAuth Server-to-Server authentication for Adobe Firefly Services — token retrieval, refresh-before-expiry, scope selection, multi-tenant credential isolation, and the JWT-to-OAuth migration path. Use whenever the user needs to obtain or refresh a Firefly Services access token, mentions "token expired", "401 Unauthorized", "auth", "IMS", "scopes", "client credentials", "S2S", "Server-to-Server", "JWT migration", or wires authentication into a service that calls `firefly-api.adobe.io` or `image.adobe.io`. Also handles JWT deprecation — JWT reached end-of-life June 30, 2025 and all certificates expired March 1, 2026; any remaining JWT integration is already broken and this skill covers the rebuild path. Do NOT use for first-time project setup; use `firefly-services-bootstrap` instead.
