/* ============================================================================
   PACKPRO — SHARED STYLES
   ============================================================================
   Design tokens and the components that appear on more than one page: buttons,
   header, footer, product cards, the sticky mobile bar.

   Every page links this file, so a colour or radius changed here changes the
   whole shop. Page-specific styling (the hero, the promo band, the checkout
   form) stays inline on its own page.

   Rules below were moved out of index.html unchanged — the look is identical.
