notes: >-
  Every request needs a Rainbrand API key (bloom_sk_...) or a Rainbrand OAuth access
  token. The key is accepted in either header; x-api-key wins when both are
  present. OAuth tokens resolve to the same user identity as an API key (same
  access to brands, images, credits, plan gates, workspaces). Public clients
  use Authorization Code + PKCE S256 with dynamic client registration and no
  client_secret; wildcard redirect URIs are not supported. Keys are generated
  at https://www.rainbrand.com/settings#api-keys.
