# wadamesh app+language store deploy: publish deploy/apps/ to the firmware VPS.
#
# The device reads BOTH catalogs from the firmware host, NOT the site host:
#   http://firmware.wadamesh.com/apps/apps.json          <- Store > Apps
#   http://firmware.wadamesh.com/apps/langs.json         <- Store > Languages
#   http://firmware.wadamesh.com/apps/lang/<ver>/<code>.lang
# so this tree lives under the FIRMWARE web root, alongside releases/ and latest*/.
#
# WHY THIS SCRIPT EXISTS: there wasn't one. release.sh rsyncs out/firmware/ (which
# does not contain apps/) and deploy-site.sh rsyncs deploy/site/ — so the store was
# only ever updated by someone remembering to rsync it by hand, and twice they did
# not. Translations sat at v8 on the server while the repo had v9/v10/v11, and a
# published app never appeared at all. Editing deploy/apps/ is not publishing it;
# running this is.
#
# Usage:
#   WADAMESH_VPS=user@your-vps scripts/deploy-apps.sh             # deploy
#   WADAMESH_VPS=user@your-vps scripts/deploy-apps.sh --dry-run   # preview only
#
# Optional:
#   WADAMESH_FW_PATH=/srv/wadamesh/firmware   # override the firmware web root
#
# The VPS target comes from the environment — never commit it.
