/* ===========================================================
   Direction A — Mobile + Responsive Pass (2026-05)
   Wird *nach* style.css geladen — überschreibt fixe Breiten
   und Pixel-Paddings für < 1440px.

   Strategie:
   - Page-Shell von fix 1440px auf fluid (max-width 1440px, w 100%)
   - Container-Padding fluid via clamp()
   - Sektions-Grids brechen auf < 960px (Tablet) und < 640px (Phone)
   - Hero h1 + Section-h2 fluid via clamp()
   - Nav: Hamburger ab < 880px
   - dirA-os: 2 Spalten ab < 720px, App-Höhe reduziert
   - Footer / Stats / Process / Tools / Personas / Tiers / People:
     auto-fit Grids mit minmax
   - Touch-Targets >= 44px auf Mobile
