# -----------------------------------------------------------------------------
# cameleer-website — Deploy to Hetzner Webhosting L
#
# Runs ONLY on pushes to `main` and on manual dispatch from the Gitea UI.
# Does NOT run Lighthouse CI (that's in ci.yml — assume any commit that reached
# main already passed the full gate). Rebuilds fresh, runs the TBD guard, and
# rsyncs `dist/` to the origin over SSH with host-key pinning.
#
# Runner: self-hosted arm64 Gitea runner. Adjust `runs-on` if your runner's
# labels differ. Deploy target is Hetzner amd64 — arch mismatch is a non-issue
# because the bundle is static HTML/CSS/JS.
#
# Required secrets (repo settings → Actions → Secrets):
#   SFTP_HOST, SFTP_USER, SFTP_PATH, SFTP_KEY, SFTP_KNOWN_HOSTS
# Required variables (repo settings → Actions → Variables):
#   PUBLIC_AUTH_SIGNIN_URL, PUBLIC_AUTH_SIGNUP_URL, PUBLIC_SALES_EMAIL
