+- `pantalla_unirse.dart`: usa `signal_art.png` como arte de conexi?n manteniendo formularios, discovery, QR scanner y estado en Flutter.
+- `pantalla_lobby_host.dart`: usa `signal_art.png` como cabecera visual y `qr_frame.png` como overlay, manteniendo `QrImageView` real.
+- `pantalla_fin_partida.dart` y `pantalla_fin_partida_online.dart`: usan `cinematic_burst.png` en el hero de resultados, manteniendo textos, progreso, historial y navegaci?n como widgets reales.
