- infra/deploy/deploy.sh <dev|prod> [ref]: git archive → scp → remote.sh на сервере;
  руками и из CI, хост — DEPLOY_HOST (любой Docker-хост); каждый шаг с ретраями
- remote.sh: атомарная замена app/ (app.old для отката), compose -p tgit-<env> up --build,
  ожидание healthy, REVISION, подсказка отката при неудаче; безопасно перезапускать
- окружение без /srv/tgit/<env>/.env пропускается (prod — когда будет свой токен)
- .gitea/workflows/deploy.yml: push в dev/main → deploy; guard «актуален ли пуш», ключ через env
