 ## Prereqs
 
 - Forgejo Actions enabled on the repo.
-- Forgejo Actions secret `AGE_FORGE_SSH_KEY` set to the SSH private key used to decrypt repo-encrypted age secrets.
-- `secrets/cloudflare-api-token.age` present in-repo and decryptable by `AGE_FORGE_SSH_KEY`.
+- Preferred: Forgejo Actions secret `CLOUDFLARE_API_TOKEN` set to a scoped Cloudflare API token.
+- Fallback: Forgejo Actions secret `AGE_FORGE_SSH_KEY` set to a dedicated CI SSH private key that can decrypt `secrets/cloudflare-api-token.age`.
+
+Do not put a personal SSH or encryption key in Forgejo Actions. Use a scoped Cloudflare token or a dedicated CI identity.
