Then everything went silent. The next morning, a librarian found Mateo’s phone on the floor, screen cracked, battery dead. On it, a single audio file was recovered. File name:

“Act One. The rain falls on a city that forgot how to listen…”

The app’s red record button blinked once.

And somewhere, in a server farm no one can trace, a waveform pulses patiently. Waiting for the next person who needs just one more audio track.
