 * Divi stacking context neutralisers:
 * Divi sections/rows/modules with will-change, transform or overflow can trap
 * position:fixed children. Since we teleport the modal to <body> via JS these
 * selectors are a safety net for edge cases (e.g. page builders that re-insert nodes).
 * We do NOT set transform:none globally (breaks animations) — only on the overlay itself.
