   DEMO · flow-systems · estilos propios (specialty Systems, acento teal) · R4
   Escenario persistente ("fs-stage"): app frame oscuro con SIDEBAR y chrome
   que nunca se desmonta (mata el vacio negro de la r3). Los capitulos rotan
   dentro de fs-stage__body con beatSwap. Nivel "escena grande": chat con
   cara real + chip de problema (11:52 pm), calendario mini con el slot
   sellado, pipeline VIVO (columnas con fantasmas y contadores) y el cierre
   de propiedad con nota flotante. El hilo conductor (fs-thread, con cara)
   hace hand-off en el swap 2->3 (r3 fix V-06). Solo tokens de la casa,
   prefijo .demo--flow-systems.
