/* ==========================================================
   SERIES GRID - Safari-safe version
   Zamiast aspect-ratio (który w Safari w kombinacji z grid +
   object-fit: cover powoduje nadmierne kadrowanie zdjęć i
   zapadanie się odstępów) używamy twardej wysokości
   obliczanej przez clamp() z szerokości viewport-u.
   Dzięki temu grid ZAWSZE ma zdefiniowaną wysokość,
   a 1fr wiersze w img-stack też ją mają - więc gap faktycznie
   działa i object-fit kadruje prawidłowo.
