Collaborative Music with Elm and Phoenix
summary
Builds a collaborative music editor using Elm frontend and Phoenix channels with Web Audio via ports and an elm-phoenix-socket library. Per-song state lives in a GenServer and the channel serializes access by replacing entire song state on updates, which is simple and works for small songs but not for high-frequency games. Demo runs and shows live edits syncing, tests exist, and the UI uses union types to make the wizard state impossible to represent invalidly.
