   MOBILE NAVIGATION (hamburger + drawer) — added 2026-05-06
   ──────────────────────────────────────────────────────────────────────
   The desktop navbar lays out as logo + nav + cta in a row. On phones
   (<= 900px) the centre nav and the right-side ISO caption + Contact
   button are HIDDEN, replaced by a hamburger that opens a full-width
   drawer with every link.

   Why 900px not 768px: under body{zoom:0.8} (which we keep on phones for
   layout consistency below 700px), 900 CSS px renders ~720 actual px —
   a comfortable point to switch from condensed desktop nav to drawer.

   ──────────────────────────────────────────────────────────────────────
   The site uses body{zoom:0.8} for desktop layout density. On phones
   (<= 700px) we restore zoom:1 because:

     1. iOS Safari and Android Chrome interpret `zoom` inconsistently
     2. Combined with viewport meta tag, can produce subtle horizontal
        scroll and broken vh calculations
     3. At phone widths, the desktop density isn't relevant — content
        already stacks vertically

   We keep zoom:0.8 between 700-900px (small tablet / large phone in
   landscape) where it still gives useful density. Below 700px, the
   real device pixels drive layout 1:1.
