   bl-phases — Slider de fases con fondo partido (color + imagen)
   blomon-base · vanilla, sin dependencias

   La composición se ancla a un MARCO de 1680 px máximo, no al viewport:
   el corte, el ancho del texto y los márgenes guardan siempre la misma
   proporción. El color sangra por la izquierda; la imagen ocupa solo su
   mitad, así el "cover" se centra sobre la parte que de verdad se ve.
