/* Opticentro · Maqueta Sense · "Laboratorio de precisión"
   Referencia: diseño suizo aplicado a una clínica óptica. Tipografía Outfit en mayúsculas light / extra bold
   con tracking 150, cuerpo en light, panel oscuro para el formulario y el chartreuse como único acento.
   Línea gráfica oficial: Pure White #FFFFFF, Jet Black #343434, Battleship gray #868F8E,
   Chartreuse #D4FF02. El chartreuse es el UNICO acento (sobre oscuro como color de acción; sobre blanco
   solo en marcas, subrayados y estados; texto sobre chartreuse = Jet Black).
   Limpieza visual: sin rejilla de fondo, sin reglas de graduación, sin escalas de
   optotipos ni numeraciones decorativas. Solo filetes finos que ordenan listas y formulario. */
