   WEB-STUDIO — BASE.CSS  ·  ESTRUCTURA (NO TOCAR POR SITIO)
   -----------------------------------------------------------------------------
   Esto es el ESQUELETO: layout, grid, nav, hero, secciones, formularios,
   footer, banner de cookies y responsive. Probado en balartre.com +
   miaminmobiliario.com. NO contiene decisiones de marca: todo color, tipografía
   y decoración viene de variables CSS definidas en theme.css.

   El "look" de cada sitio se hace SOLO en theme.css. Si necesitás un layout
   nuevo (otra sección, otra grilla), agregalo acá UNA vez y queda para todos.

   Contrato de variables (las define theme.css :root):
     --font-display, --font-body
     --color-ink, --color-bg, --color-bg-alt, --color-muted, --color-rule
     --color-accent, --color-on-accent, --color-on-dark
     --radius, --maxw
