Module login 

OAuth authorization-code login for channels (§14.5).

Channel covers per-request upstream access and the silent refresh_token rotation; ChannelLogin is the orthogonal first-time credential acquisition — the interactive authcode + PKCE dance that mints the very secret a channel later refreshes. A channel may impl one, both, or neither (an API-key channel impls neither).

Pure async + serde_json — no cipher, no persistence, no axum. Compiles on native AND wasm (the registry that holds these is used on every target); the admin HTTP endpoints that drive the flow are native-only. The dual #[cfg_attr] async_trait Send/?Send split mirrors Channel.
