/* =========================================================
   RESPONSIVE — productie-layout voor mobiel/tablet/desktop.

   Standaard: schone productie-look (geen demo-rail, geen
   telefoonframe). Met `?demo=1` in de URL wordt body.demo-mode
   gezet, dan zie je de oude demo-stage met phone-mockup en rail.

   Breakpoints:
     - <640px        Mobiel: app vult het scherm
     - 640-1023px    Tablet: app gecentreerd, max-width 720px
     - >=1024px      Desktop: nav als zijbalk + content gecentreerd
