# Declarative facet behavior: echo OBSERVES nothing on the filesystem — it prints its literal
# arguments to stdout (which reaches the model), touching no file, network, process, or secret.
# A none-role emitter: its `-n`/`-e`/`-E` flags only format the output, and any other argument is
# just printed. Redirection (`echo x > f`) is a separate capability the enclosing CST resolves.
# Replaces `resolve_echo`.
