// Trusted devices on the SSO paths. The gap these lock down: SSO used to jump
// straight from needsTotp() to staging a challenge, so a browser the user had
// explicitly trusted was still asked for a code on EVERY Google/Discord sign-in,
// and the SSO second step had no way to establish trust at all.
//
// Covered here:
//   - a trusted device (bound to THEM) skips the SSO second factor;
//   - a trust bound to a DIFFERENT user is ignored — challenge as usual;
//   - a store error falls back to the challenge (fail closed to asking);
//   - the mobile bridge (Custom Tab) gets the same skip;
//   - POST /auth/sso/totp with trustDevice sets the trust cookie, and flags the
//     bridge session so /exchange can mint the app's own token;
//   - at the device cap the sign-in still completes, with a trustLimitReached prompt.
