/* =============================================
   PÁGINAS HUB — Fiscalidad en España (nacional.html)
   y Fiscalidad internacional (internacional.html)
   =============================================
   Depende de style.css, gestoria.css (hero, panel
   lima, modal), consultoria.css (cabeceras .cns-*,
   tarjetas oscuras, modal de contratación) y
   estructuras.css (botones del hero, pasos, "Dos
   formas de empezar", CTA final con dos botones).
   Aquí solo van las tarjetas de servicio.

   Secuencia de fondos:
   hero (negro) → servicios (claro) → cómo trabajamos
   (negro) → dos formas de empezar (claro)
   → CTA final (negro).
