/* Parent panel responsive + cross-browser overhaul.
 *
 * Namespaced via `body[data-panel="parent"]` so it doesn't bleed into the
 * other 5 panels (school / teacher / cafeteria / seller / admin).
 *
 * Mirrors the cafeteria-responsive.css pattern (sections 1-21 + Phase 2
 * a11y M-U + polish V-AE + critical sticky fix) but tuned for the parent
 * panel's purple identity. Reuses every lesson learned during the
 * cafeteria 2026-05-26 marathon.
 *
 * Load order:
 *   <link rel="stylesheet" href="/css/parent-responsive.css?v=N">
 *   <script src="https://cdn.tailwindcss.com"></script>
 *
 * Tailwind comes AFTER so its utilities still win where we want them.
 * Our overrides target areas Tailwind can't reach (vendor prefixes,
 * RTL-aware logical properties, safe-area-inset, focus-visible).
