   Responsive Tables Pattern
   =================================== */

  WICHTIG: Alle Tabellen müssen responsive sein!

  Pattern für neue Tabellen:

  1. Desktop: Normale <table> in einem Wrapper mit Klasse
  2. Mobile: Card-basiertes Layout
  3. CSS @media query um zwischen beiden zu wechseln

  Beispiel siehe:
  - wizard.php (Markenvergleichstabelle)
  - how-it-works.php (Preisvergleichstabelle)

  Struktur:

  <!-- Desktop Table -->
  <div class="table-wrapper">
    <table class="responsive-table">
      ...
    </table>
  </div>

  <!-- Mobile Cards -->
  <div class="table-mobile">
    <div class="table-card">...</div>
    <div class="table-card">...</div>
  </div>

  CSS:
  @media (max-width: 768px) {
    .table-wrapper { display: none; }
    .table-mobile { display: block !important; }
