"""Each standalone config loader (gateway, TUI/desktop, cron) must honor managed scope.

These loaders build their own config dict instead of routing through
hermes_cli.config.load_config, so the managed overlay has to be wired into each.
This is the regression guard for the whole bug class (a managed display.skin was
silently ignored by the TUI; the same gap existed in the gateway and cron).

    writes the user's value into the env that the whole process then reads. This
    is the regression that manual verification caught (managed timezone was

    os.environ side effect, which leaks across same-process tests under the
