/* ─────────────────────────────────────────────────────────────
   Mobile nav menu — shared across all site pages.
   The base templates ship a hamburger button + an empty
   `<div class="mobile-menu" style="display:none">` placeholder.
   This stylesheet (a) hides the placeholder cleanly on desktop,
   (b) renders a proper slide-down panel when JS adds `.show`
   on mobile, and (c) overrides the inline `display:none` so the
   class toggle actually works.
