/* Entreno — Liquid Glass (material Apple) + Paleta A de Vadric (color).
 *
 * Del Liquid Glass de iOS 26 se toma el MATERIAL: capas translúcidas con blur
 * y saturación, highlight especular en el borde superior, profundidad por luz
 * y no por contorno.
 * De Vadric se toma el COLOR: tinta / hueso / latón. Nada de #F7E45F (ese es
 * de SentryIQ, producto — no toca esta app).
 *
 * Tipografía: pila del sistema. SF Pro en iPhone, Roboto en Android. Es la
 * tipografía nativa del Liquid Glass y evita descargar fuentes, que rompería
 * el "todo local, cero red".
