Local development agreement

Source lives locally under ~/projects/fzc-src/cube; fzc is the deployment target, not an interactive development workspace.
Use the root Makefile for routine deployment. Preserve existing data, credentials, ingress, service names and schedule.
Never bulk-deploy, trigger real notifications, or import production data merely to verify a migration.
Original unrelated dirty files belong to the user; preserve them and review before committing/publishing.
Do not commit local config files, caches, login images, backup credentials or runtime records.
Read README.md for the exact deployment boundary. Other projects/hosts are outside this repository's scope.
