feat(hilo): retira el hilo conductor de la página

La dueña pidió quitarlo. Con él se van las dos cosas que solo existían para sostenerlo: el `relative` de <main> —ninguna sección lo necesita, todas son relative por su cuenta salvo Disciplinas, que no tiene hijos absolutos— y el export RADIO_BARRA, sin consumidores. BARRAS_SIMBOLO se queda como forma canónica del ≡ aunque ya nadie dibuje las barras: LINEAS_SIMBOLO se deriva de ella y el test que obliga a las dos representaciones a coincidir es lo que mantiene honesta la geometría frente al Manual.
