There are no files to deploy here — and that's correct.
In Open Stage Control, the client is your web browser. The Open Stage Control
server (running on the remote Mac, see ../server/) serves the
UI over HTTP. You don't host or copy anything onto a separate web server.
To use the control surface, open a browser on any device on the same network as the remote Mac and go to:
http://10.112.10.50:8080
That page is the client. Drag the stage, add emitters, etc. — the server translates your actions into SPAT5 OSC and sends them to Pd.
The UI layout itself lives in ../server/osc/session.json
(generated from TypeScript in ../src/session/) because it is
loaded and served by the server process — not stored here.
