/* ============================================================
   NINJA* (lafour_theme) — work.css
   Sección Work: índice en rejilla (tarjeta adaptada del pen
   «Responsive News Card Slider») y ficha con vídeo en modal
   y galería en mosaico.

   Del pen se conserva la anatomía de la tarjeta (meta, título,
   extracto y la imagen abajo) y el bloque de fondo que se
   desplaza al pasar el ratón. Se descartan sus colores, el
   carrusel y sus dependencias.

   El rojo de marca NO se usa como relleno grande (véase la nota
   de base.css): el bloque activo va en --c-surface-2 y el acento
   rojo entra como filete superior.
