   MOBILE SAFETY NET

   1) iOS Safari automatically zooms the page whenever a form control with
      a font-size under 16px receives focus. That zoom is never undone, so
      the visitor is left on a shifted, oversized layout. Forcing 16px on
      small screens prevents it entirely.
   2) A hard guard against horizontal scrolling, which is the most common
      way a page "feels broken" on a phone.

   MOBILE MENU FIX
   ---------------------------------------------------------------------
   .nav uses backdrop-filter for its frosted-glass effect. Per the CSS spec,
   any element with a backdrop-filter becomes the CONTAINING BLOCK for its
   position:fixed descendants. That means the mobile menu panel was being
   positioned against the header strip instead of the viewport, so it
   appeared short and see-through rather than as a full-height solid panel.

   MOBILE MENU FIX v2 - stacking context correction
   ---------------------------------------------------------------------
   .nav is 'position: sticky; z-index: 50', which CREATES A STACKING
   CONTEXT. Every descendant is therefore confined to level 50 relative to
   the page, no matter how large its own z-index is.
   The dimming overlay (body::after) lives in the ROOT stacking context at
   z-index 1100, so it was painting OVER the menu panel - making a solid
   white panel look like a dark translucent one.
   The correct fix is to lift the whole .nav element above the overlay while
   the menu is open. Then the panel paints above the dim layer.

   A dark navy matte panel with hairline gold waves drifting through it.

   Layer order (top to bottom):
     1. gold wave SVG   - the texture
     2. soft radial     - a gentle sheen so the panel is not flat
     3. linear gradient - the matte navy base

   The waves are drawn as a percent-encoded inline SVG, so they cost no
   extra request and stay crisp at any pixel density.
