/* ══════════════════════════════════════════════════════════════════════════
   Shared site navigation — Caregivers Asha Society
   ──────────────────────────────────────────────────────────────────────────
   Loaded LAST on every page (after each page's own inline <style> block), so
   these rules win on source order without needing !important.

   The drawer takes over below 1021px. The full desktop nav measures ~975px
   wide (logo + six items + the two buttons), so switching any earlier than
   that would hide navigation people have room for.

   Two things live here:
     1. The mobile drawer. styles.css already ships a checkbox hamburger, but
        every page's inline CSS re-hid .nav-links at its own breakpoint with no
        :checked override — so on a phone the menu vanished with no way to open
        it. Fixed here, once, for all pages.
     2. The "Featured" submenu. Pure CSS: hover and focus-within on desktop,
        always-expanded inside the drawer. No JavaScript required.
