 * Z-index override for dropdowns inside backdrop-filter stacking contexts.
 *
 * `backdrop-filter` creates a CSS stacking context. Bootstrap's default
 * z-index for .dropdown-menu is 1000, which is fine globally. But inside
 * a stacking context, z-index values are scoped — the dropdown must be
 * ABOVE all sibling elements within that same stacking context.
 *
 * .pf-navbar    → z-index: 1030 (stacking context via backdrop-filter)
 * .pf-sidebar   → z-index: 1040 (stacking context via position:fixed + z-index)
 * .pf-home-nav  → z-index: 1000 (stacking context via position:fixed + z-index)
 *
 * Setting dropdown z-index higher than the parent's own z-index ensures
 * the menu renders on top of everything within that context AND appears
 * above sibling layout elements at the document stacking level.
