/* ===================================================================
   MOBILE-ONLY UI/UX POLISH
   Every rule in this block is scoped inside @media(max-width:640px),
   which targets phones specifically (not tablets — those keep the
   existing ≤900px stacking rules defined earlier, untouched). Nothing
   here modifies any base/desktop rule; it only adds overrides that
   apply exclusively below 640px, so desktop and tablet are guaranteed
   pixel-identical to before.

   Design system for this breakpoint: 4px spacing scale (8/12/16/20/
   24/32/40/48), 16px minimum on all form inputs (prevents iOS Safari's
   auto-zoom-on-focus — a real, well-known mobile UX bug below that
   threshold), 44px minimum tap targets, and consistent 14px card
   radius with a soft shadow for a bit of depth instead of flat borders.
