// Webinar replays — members-area page. The list comes from /api/public/replays:
// locked responses carry titles/dates only (prospects see the shape of the
// product), a member session gets the video URLs. Unlock is the same
// one-signature SIWE flow as the training page (msg-challenge/msg-verify via
// RMCWallet); Mini App visitors already carry a session and see no lock.
