    13. Motion, reduced motion, forced colours

   Breakpoints (mobile-first; only these four widths are used)
     480px   large phones   header "Español" shows its text label
     640px   tablets        two-column grids, header portal button always shown
     960px   laptops        side-by-side layouts, hero artwork
     1200px  desktops       roomier proportions
   The header's section nav uses the same widths written in em (60em = 960px, 75em = 1200px
   at the normal text size), so it steps aside when a visitor enlarges the browser's text size.
   "max-width" queries use the value minus 0.02px (e.g. 639.98px, or 74.99em) so ranges never overlap.
   The "Contact me" card also adapts to its own width with container queries (270 / 540 / 1080px).
