/* ── Guest name gate (guest mode) ─────────────────────────────────────────────
   Rendered as a full-viewport fixed overlay so it always appears, regardless
   of how the host theme styles or positions the shortcode container. Themes
   like Divi often wrap shortcodes in elements with overflow:hidden, transform,
   or filter, all of which break position:absolute children. Using fixed +
   !important on the layout properties + id selector for higher specificity
   defeats those conflicts.
