  // ── Sign in with Nextcloud ────────────────────────────────────────────
  // Nextcloud's own login flow: ask our server to start one, send the person to
  // the URL Nextcloud hands back, and poll until they finish.
  //
  // The first version opened a blank tab during the click and pointed it at the
  // URL once the request came back, which is the usual way around a popup
  // blocker. It cannot work here: this app sends
  // Cross-Origin-Opener-Policy: same-origin, so the handle to that tab is
  // severed the moment it goes cross-origin, and assigning its location did
  // nothing at all — a blank tab, and a button that looked broken.
  //
  // So no handle. window.open with 'noopener' needs none, and a click's user
  // activation survives the fetch, so it is not treated as a popup. And the
  // status line always offers the link itself, which works whatever the browser
  // decides about opening windows.
