/* ===== Gasfitería MJ — styles.css (v1) =====================================
   Sistema propio. NO comparte tokens ni layout con jyrgasfiteria.cl: ese sitio es
   navy oscuro + naranja con hero full-bleed; este es claro, cian/grafito y hero
   partido con la tarjeta de cotización sobre el pliegue. Dos activos del mismo
   rubro que se ven iguales compiten entre sí y se leen como plantilla — la
   separación visual es un requisito del proyecto, no una preferencia.
