/* --- INSTRUCCIONES PARA HTML Y JAVASCRIPT --- */
/*
    Para que el menú hamburguesa funcione, necesitas hacer dos pequeños cambios:

    1.  En tu archivo HTML (index.php), añade este botón DENTRO del .nav-container,
        justo después del .nav-brand y antes del .nav-menu:

        <button class="hamburger" aria-label="Abrir menú" aria-expanded="false">
            <span class="hamburger-box">
                <span class="hamburger-inner"></span>
            </span>
        </button>

    2.  En tu archivo JAVASCRIPT (script.js), añade este código para que el botón
        funcione al hacer clic:

        document.addEventListener('DOMContentLoaded', () => {
            const hamburger = document.querySelector('.hamburger');
            const navMenu = document.querySelector('.nav-menu');

            if (hamburger && navMenu) {
                hamburger.addEventListener('click', () => {
                    hamburger.classList.toggle('is-active');
                    navMenu.classList.toggle('is-active');
                    
                    const isExpanded = hamburger.getAttribute('aria-expanded') === 'true';
                    hamburger.setAttribute('aria-expanded', !isExpanded);
                });
            }
        });
