/* =========================================================
   Proyectos (/proyectos/) — encabezado nuevo, encabezado del
   portafolio y tarjetas de proyecto con panel de vidrio esmerilado.
   Esta hoja solo se carga en /proyectos/index.html, después de
   main.css y header.css. Todas las reglas de tarjeta van bajo
   .projects-grid para no tocar el .project-card base de main.css.
   Vidrio: misma receta que .sol-card de servicios.css (tinte --ink,
   blur, borde translúcido, radio); aquí la foto da la textura.
