   Los Altillos — Cómo instalar Durlock paso a paso
   Archivo: assets/como-instalar-durlock.css
   Prefijo: lainst-  (hub /drywall/ y demás subpáginas no se pisan)
   Molde: argentina/tema/assets/guia-steel-framing-argentina.css (sfgag-):
   mismo esqueleto, hero, tipografía, callouts, tablas, FAQ e índice.
   Propio de esta página: el tabique visto de frente en HTML/CSS (la pieza
   fuerte), los pasos con «comprobación», la tabla T1/T2, las capas del
   tomado de juntas, la cadena «hago / compruebo» y la revisión final.
   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.
