# wadamesh site deploy: publish the static landing page (deploy/site/) to the
# VPS web root behind Cloudflare.
#
# The apex `wadamesh.com` nginx block serves /srv/wadamesh/site
# (flasher.wadamesh.com 301-redirects there), so that dir IS the live site.
#
# Usage:
#   WADAMESH_VPS=user@your-vps scripts/deploy-site.sh             # deploy
#   WADAMESH_VPS=user@your-vps scripts/deploy-site.sh --dry-run   # preview only
#
# Optional:
#   WADAMESH_SITE_PATH=/srv/wadamesh/site   # override the web root
#
# The VPS target comes from the environment — never commit it (Cloudflare fronts
# the origin, so the IP isn't needed in the repo).
