// Body shape for tessera's social sign-in wrapper at POST /api/sign-in/social.
// Factored out of sign-in.tsx so the `oauth_query` forwarding logic can be
// unit-tested without DOM.
//
// `oauth_query` is the signed query string from /authorize (sig + exp
// included). The wrapper attaches it to Better Auth's `additionalData` so
// oauth-provider's before-hook captures it into oAuthState and the user
// resumes the signed RP flow after the IdP round-trip.
