# zdeploy — deploy any project defined in zconfig.json to the server.
# Each project runs its own docker compose stack; the handler is picked by the
# project's "kind": python | vite | nextjs | edge | docker.
#
# Usage:
#   zdeploy <project> [<project> ...] [--note "message"]
#   zdeploy all                       # every project (edge kinds first), stop at first failure
#
# Flow (python/vite/nextjs): zip source -> free server disk space -> scp up ->
# unzip into remote.path (preserving server-side .env) -> docker compose build + up
# -> verify the live site reports the new build version. Zips are always deleted.
