/* ============================================================
   Landing de campaña "seafood-2026" — adaptado del diseño real
   publicado en https://www.ibercook.com/seafood-2026 (hero a sangre +
   H1 centrado + sección a 2 columnas formulario/texto).

   Autocontenida a propósito: NO importa ibercook.css (la plantilla
   está aislada del resto de la web), así que los tokens de color y
   tipografía se redeclaran aquí mismo con los mismos valores que ya
   usa la web ya rediseñada (coinciden con los colores reales de la
   página legacy: navy #455674, rojo #cf0a2c). Cada campaña nueva
   puede cambiar este bloque :root por su propia paleta sin afectar
   a ninguna otra landing ni a la web.
