The arcade is a single browser app shaped like a CRT terminal. The index is a "library card" of seven games; each one sits in its own SvelteKit route so you can hot-swap between cartridges without reloading. We split work along the SIGNAL theme deliberately — every game is the same word turned a different way:

• Routing it through circuitry (Signal Grid)
• Weaving it with a partner (Signal Weave)
• Patching it through a 1962 switchboard (Signal Cross)
• Racing it through tracks of relays (Signal Surge)
• Decoding it off a 3D tabletop (Deconstruct)
• Hiding inside it in a haunted relay station (Dead Air)
• Flashing it across reefs from a lighthouse (Semaphoria)

All multiplayer cartridges share the same shape: open channel → copy code or link → BEGIN. PeerJS gives us serverless WebRTC; URLs of the form ?room=CODE auto-join when opened.
