/* Sign-in modal ------------------------------------------------------------
   Shown to logged-out visitors who click a login link on desktop, so a gated
   article does not throw them onto a separate page and lose their place.
   Narrow viewports skip the modal entirely and follow the link (see
   login-modal.js) -- a fixed overlay competes badly with a phone keyboard. */
