+# Manual PROD deploy to Portainer.

+# This does NOT build — build.yml already builds + pushes the api/web images.
+# This workflow (re)applies the deploy/*.stack.yml files to the Portainer Swarm.
+# Trigger it by hand from the Actions tab ("Run workflow") and choose:
+#   - tag:   which already-published image tag to ship (default: latest)
+#   - scope: how much to deploy
+#       app  = web + api only (the usual app release)      [default]
+#       full = db + minio + web + api (bring up / update the whole platform)
+#
+# cssnr/portainer-stack-deploy-action creates each stack on first run and updates
+# it on every run, so no manual stack pre-creation in the Portainer UI. On a
+# `full` deploy the db + minio stacks are applied BEFORE the app (the API depends
+# on them). db + minio are stateful + pinned to node label jorgecuadros_db=true
+# (see their stack files) — re-applying them is idempotent and keeps their data.
