/// file from your config — the environment variables, aliases, and
/// per-package init lines declared by your `[pkg.*]` entries. During
/// `apply` zenops compares the derived file against what's already on
/// disk and walks you through any differences hunk by hunk, so the file
/// only changes when you say so. You source the result from your real
/// `.bashrc` or `.zshrc` and the rest is hands-off.
///
/// Pick `type = "none"` to keep managing your shell by hand — zenops
/// won't derive or compare anything, but you also lose the per-package
/// shell init.
