/*
 * Estado abierto del menú escalonado.
 *
 * Va en una hoja propia y no en el sistema de diseño porque el compilador de
 * clases del editor descarta estas reglas: las que dependen de una clase que
 * ningún nodo lleva (.sm-open, .is-open) desaparecen enteras, y de las
 * .sm-cb:checked ~ … solo emitió una de diez. Aquí el CSS se sirve tal cual.
 *
 * Abrir y cerrar es un <input type="checkbox"> oculto con su <label>, así que
 * el menú funciona sin JavaScript. La coreografía reproduce la del
 * StaggeredMenu de React Bits con transiciones y retardos:
 *
 *   capas 0 s y 0,07 s → panel 0,15 s → líneas 0,25 s (+0,1 s cada una) →
 *   numeración 0,35 s (+0,08 s) → contacto 0,41 s (+0,08 s)

 * Batería pieza a pieza — sección 3D de la página CEO (#pieza-a-pieza).
 *
 * Un escenario fijo a pantalla completa que avanza con un recorrido de scroll
 * muy largo: el equipo se monta, sigue dando luz en un apagón, se vuelve nueve
 * equipos en paralelo y acaba cargándose de varias fuentes para alimentar la casa. Textos del paso a la izquierda, lista de piezas (luego
 * el esquema de energía) a la derecha. En el apagón el escenario se oscurece.
 * En móvil el texto pasa a una tarjeta abajo.
 *
 * Todo va con prefijo bat- para no tocar las clases del sitio, y en px porque
 * el sitio usa html { font-size: 62.5% }. El escenario se pega debajo de la
 * cabecera (.hdr mide 57 px con su borde).
