This repo ran its own separate copy of Postgres, Zitadel and SeaweedFS,
none of which are actually wired into the Go backend yet (auth and file
storage are still unchecked TODOs in the README). Removed that unused
duplicate stack (deploy/docker-compose.dev.yml, deploy/postgres-init/)
in favor of the shared Infrastructure repo also used by Musify and Ping.
make dev-infra now brings up Infrastructure instead, and backend/.env.example
points at its ports (Postgres on dockermanager_db, Zitadel, SeaweedFS)
as placeholders for when those features are implemented.
Remove Go doc comments, TS/Svelte scaffold comments and explanatory
notes left over from the initial scaffold, plus a few leftover Spanish
notes in the compose file, SQL scripts and env template. Also drops
frontend/src/lib/index.ts, which only held the SvelteKit placeholder
comment and was never imported.
