Session notes.
Pause, reload & saved progress
Pause using the game’s own controls before leaving. SENOVIRA cannot reliably pause or mute an external game. Reload restarts the frame and may discard unsaved progress; Unload removes it. Neither clears the game’s storage. Browser privacy settings may separate embedded and direct saves.
