// Multi-tenant mode (a.k.a. cloud mode) turns the self-hosted Recaps
// into a multi-user app served over the web. Adds email + magic-link
// auth, per-user libraries, per-user keysat licenses, and BTCPay-based
// subscriptions. The .s9pk defaults to single-mode (one operator, no
// auth) so installing Recaps doesn't surprise anyone — multi is the
// deliberate opt-in for operators who want to host the app for others.
//
// Prerequisites before enabling:
//   1. StartOS System SMTP must be configured + tested. Magic-link
//      emails fail otherwise.
//   2. "Set Recaps public URL" action must be run with the ClearNet URL
//      where your Recaps will live (e.g. https://recap.example.com),
//      so the sign-in emails contain a working link.
//   3. A keysat issuer the relay trusts must be reachable, since each
//      cloud user gets a keysat-minted license at signup.
//
// Switching back to single mode is non-destructive — multi-tenant data
// (the user DB at /data/recap.db) stays on disk and is restored if you
// flip back to multi later. The operator-owner's library lives under
// /data/history/owner/ in either mode.
