   Pagina PROJECTS - EN /projects/ - ES /es/proyectos/
   V3 "THE SILVER STANDARD": tinta #0A0A0B / #101013, papel #FBFBFA,
   UN acento #FE7300, hairlines, Anton display, eyebrows "//", fotos
   reales SIEMPRE en placa/marco etiquetado dentro del mundo oscuro.

   FRONTERA: este archivo es el UNICO CSS de esta pagina. base.css,
   js/main.js y js/boot.js no se tocan.

   ESTRUCTURA (ley 0720-a #11: dos galerias con banner de seccion EN MEDIO)
     banner (tinta+foto) -> intro (tinta) -> GALERIA 1 bento (ink2)
     -> BANNER INTERMEDIO escena (foto) -> GALERIA 2 desfasada (tinta)
     -> antes/despues (ink2) -> CTA foto scrim horneado -> footer

   Compositor-only: aqui no se anima width/height/filter/top/left.
   GSAP (projects.js) es dueno unico del transform de .gt y de los <img>
   con zoom; las unicas transition CSS viven en opacidades de pseudos y
   colores, nodos que GSAP no posee.
