The previous version was in Dutch and hardcoded internal deploy details
(hostname alias, personal local path, private Gitea mirror domain) that
had no business being in a public repo. Replaced with a generic version
using <docker-host> placeholders; the internal nc01-specific copy now
lives at notes/deploy-nc01.md, which is gitignored and stays local-only.
Not rewriting prior history for this (confirmed with user: nothing
credential-level was exposed, just a hostname alias and a path).
