/* =========================
   DeutschlandKompass – tech_futuristic UI
   Author: Senior CSS Developer & UI Designer
   Notes:
   - Mobile-first, ONLY flexbox for layouts (no grid/columns)
   - Brand fonts/colors applied with a futuristic twist (neon accents, sleek surfaces)
   - Solid color base with subtle simple gradients only where safe
   - Includes mobile menu & cookie consent styles
