/*
 * Web pública de Dentanexa: tokens, navegación, pie y cierre comunes a todas las
 * páginas públicas (home, /features, /pricing, /demo, legales).
 *
 * Fichero plano a propósito: la landing no tiene entrada de Vite. Los tokens
 * llevan prefijo --dx- y las clases dx- porque conviven con app.css (Tailwind y
 * el panel interno, que ya define --ink, --muted o .tooth) y landing-modern.css
 * (que ya define .btn-primary).
 *
 * La web pública es siempre clara, con independencia del tema del sistema. El
 * único tramo oscuro es la noche de «Un día en la clínica» (landing-home.css).
