   Los Altillos — Cielorraso de PVC (subpágina de /cielorrasos/)
   Archivo: assets/cielorraso-pvc.css
   Prefijo: lapvc-
   Molde: assets/guia-steel-framing-argentina.css (sfgag-), por la vía de
   assets/cielorraso-durlock.css (lacid-), con las correcciones de la
   verificación del lote 1 (un solo margen de scroll para el TOC).
   Propio de esta página: las barras del hero (lamas solas contra sistema
   completo), la muestra de terminación PVC / junta tomada, el veredicto
   «elegí PVC si… / Durlock si…» y la calculadora con la planta a escala.
   Depende de assets/main.css (variables de color, tipografías, reset).
   Escala propia en px: no depende de html{font-size:12px} (main.css)
   ni del :root{font-size:15px} móvil del bloque 26 de functions.php.
   Texto de lectura: 18px escritorio / 17px móvil. Nada por debajo de 14px.
