Clicking Connect always tries a steam://connect/ip:port link in your own
browser first — that's the only part of Connect that works when this page is visited over the
network, since a remote server cannot launch anything on your machine.
Only useful if this app is running on the same machine as your game — e.g. you
run node server.js locally instead of using the hosted site.
This app queries game servers directly with the standard A2S protocol. It cannot pull
play-cs.com's own list (their site is behind a Cloudflare human-verification wall), so add server IPs
manually — including any you copy from play-cs.com yourself.
