/**
 * Atiko Flipbook - Frontend styles
 *
 * NOTA SOBRE ESPECIFICIDAD:
 * Elementor (y algunos temas) aplican estilos globales a botones via selectores
 * como `.elementor-button-wrapper button` o `button[type="button"]`. Para ganarle
 * a esa especificidad sin usar !important, encadenamos clases (técnica estándar
 * de CSS Specificity Wars: clase repetida = especificidad duplicada).
 *
 * Variables CSS para fácil override desde el tema:
 *   --atiko-flipbook-btn-bg
 *   --atiko-flipbook-btn-color
 *   --atiko-flipbook-btn-bg-hover
 *   --atiko-flipbook-counter-color
 *   --atiko-flipbook-gap
