   Bayres Green — styles.css

   Única hoja de estilos del sitio. Paleta: verde natural + crema
   (adaptada de joinspread.app).

   Cada sección de la página tiene su bloque acá abajo, marcado con un
   banner como este. El orden sigue al del HTML: variables y reset →
   compartido → botones → nav → hero → marquee → intro → servicios →
   stats → proceso → galería → clientes → contacto → footer →
   estados de animación → responsive → movimiento reducido.

   Convenciones:
   - Clases con nomenclatura BEM: .bloque, .bloque__elemento, .bloque--variante
   - Colores, fuentes y medidas repetidas viven como variables CSS en :root

   Fonts: dos hojas de estilo externas que frenaban el primer pintado en el

   descarga, el texto se ve con la del sistema en vez de quedar invisible.
   Satoshi (primera en --font-display) nunca llegó a cargar desde Fontshare,
