   Everything in this file is wrapped in `@media (max-width: 768px)`.
   It is loaded AFTER all other stylesheets so it overrides them only for
   phones & small tablets. Desktop behaviour is untouched.

   Breakpoints used:
     · ≤ 768px   — mobile default (all rules)
     · ≤ 480px   — compact phones
     · ≤ 360px   — very narrow phones (iPhone SE 1st gen, old Androids)

   Touch target minimum: 44 × 44 CSS px (WCAG 2.5.5).
   iOS zoom prevention:  form inputs ≥ 16px font-size.
