/*
 * Home pública de Dentanexa. Solo la carga resources/views/landing.blade.php.
 *
 * Layout: una sola columna editorial; la arcada es el único elemento expresivo
 * y cada sección la usa con un papel distinto (cuna, puzle, reloj, boca,
 * indicador). Tokens en landing-site.css (--dx-*).
 *
 * Regla de oro: el HTML llega completo y en su estado final. Lo que se anima
 * solo se esconde bajo html.js (la clase la pone el layout antes de pintar) y
 * nunca con «reducir movimiento»: sin JavaScript no queda nada a opacidad 0.
