/* =================================================================
   PONLO EN SU SITIO — hoja de estilos (v2: sistema plano + líneas)
   Sin fondos fotográficos de escena. Paleta plana + tipografía como
   protagonista + líneas finas de 1px como único recurso decorativo.
   Los recuadros ".niche" son huecos listos para alojar una imagen
   SUELTA (como hero-object-stack.png) el día que la tengas — nunca
   un fondo de escena completo.
