# Sync admin web UI: repo -> server /mnt/web/admin
# ------------------------------------------------------------------
# Why: nginx serves the admin UI directly from /mnt/web/admin
#      (location ^~ /admin/ { root /mnt/web/; }), independent of the images.
# Usage (set SSHPASS first):
#   $env:SSHPASS='<server password>'
#   powershell -ExecutionPolicy Bypass -File deploy\sync-admin-ui.ps1
# It packs the repo dir (excluding *.bak*), uploads it, then on the server:
# back up current UI (keep latest 3), extract over /mnt/web/admin.
# Existing server-only files (e.g. *.bak) are not deleted.
