   style.css is written mobile-first (base rules = smallest screen).
   This file layers min-width media queries on top to progressively
   enhance the layout for tablet / desktop / large-desktop.

   Breakpoints (kept as plain comments — custom properties cannot be
   used inside @media conditions):
     --bp-sm: 600px   (large phones / small tablets)
     --bp-md: 900px   (tablets / small laptops)
     --bp-lg: 1200px  (desktop)
     --bp-xl: 1440px  (large desktop)
