   SHELLS Design-System — Section Card
   Globale Basis-Klasse für alle Hauptcontainer auf Versuchs-
   und Unterseiten. Ersetzt generische Bootstrap-.card-Wraps
   schrittweise (STYLE_GUIDE §2.2).

   Modifier:
     .section-card--flat    — ohne Hover-Elevation (statische Panels)
     .section-card--accent  — 4-px-Gradient-Streifen links (::before)

   Kinder:
     .section-card__header  — Titel + Actions in einer Flex-Zeile
     .section-card__title   — Card-Überschrift
