name: Deploy to Hostinger
description: >-
  rsync one plugin/theme to staging or production on Hostinger. Gitea port of the
  GitHub reusable deploy-app.yml (Gitea 1.25 has no workflow_call): same rsync
  excludes, retry-on-throttle (Hostinger rate-limits runner IPs), best-effort
  plugin-inventory guard and health check. New: records the deployed commit in
  ~/.peptide-deploys/<stage>/<target> (outside public_html) for deploy-health.
