/* ==================================================
   PIE DE PÁGINA · todo el sitio
   Prefijo bft- (único). El HTML sale de parts/footer.html (lo imprime functions.php en wp_footer).
   Variables de marca: las mismas que header.css (:root).
   Antes el pie estaba copiado a mano dentro de 5 páginas y faltaba en el resto (carrito, categorías, producto, blog…):
   ahora es uno solo y sale en todas. Los pies viejos se ocultan solo cuando este está presente.
