How it works

Start the server pointing at a PDF:

deck my-talk.pdf

Then open these URLs in your browser:

Route	Open on	Description
/deck	Projector / main display	Full-screen slide viewer
/view	Your laptop	Speaker view: current slide, next slide, clock, elapsed timer
/control	Phone or tablet	Remote control with prev/next buttons and slide thumbnail

A QR code is printed in the terminal — scan it to open /control on your phone immediately.

All devices sync in real time over WebSocket on your local network. No accounts, no cloud, no internet.
