//   - API key (sk-...)      → cloud API on api.xiaomimimo.com
//   - Desktop account/OAuth → same cloud host, plus the Desktop-exclusive Preview
//     models served by the account-service route on mimo-server-cn.xiaomimimo.com
//     (authorized by a Xiaomi account session cookie, not the key).
// Endpoint is picked per model in the executor, same as opencode-go's /responses split.
