openGym: the gym tracker you host yourself

Architecture: the phone talks HTTPS to nginx (web), which serves the app and proxies /api to the Node api; the api stores JSON in ./data. The exercise media ship inside the web image; the AI coach and MCP server are optional.

Sync: a device saves with the revision it last saw; if another device wrote in between, the server answers 409 with the current document, the device merges and saves again.

Quick install
