# Push this project to the central Gitea repository.
#
# Run this FROM REPLIT (the development environment). It pushes the `main`
# branch to the `gitea` remote so the Mac Mini can pull and redeploy.
#
#   Flow: (this script) Replit -> push to Gitea -> Mac Mini pulls -> Docker redeploys
#
# One-time setup — add the gitea remote with your Gitea repo URL:
#   git remote add gitea https://<user>:<token>@<gitea-host>/<owner>/<repo>.git
#   # or via SSH:
#   git remote add gitea git@<gitea-host>:<owner>/<repo>.git
#
# After that, just run:
#   ./scripts/push-to-gitea.sh
#
# Optional overrides (environment variables):
#   GIT_REMOTE         Remote name        (default: gitea)
#   GIT_BRANCH         Branch to push     (default: main)
#   GITEA_REMOTE_URL   If set and the remote does not exist, it is added first.
