# rustelo-content — content authoring CLI (local installation wrapper)
#
# Dispatches subcommands to the installed Nushell authoring scripts under
# $RUSTELO_CONTENT_HOME (default ~/.local/share/rustelo-content). Installed at
# $HOME/.local/bin/rustelo-content by `just content-install`.
#
# A POSIX sh dispatcher (not nu) so arbitrary downstream flags forward verbatim
# through "$@" without Nushell's custom-command flag parsing intercepting them.
#
# The underlying scripts default their paths to ./site/content, ./site/public
# and ./site/config/image-generation.ncl, so run from a site workspace root
# (the dir containing site/), exactly like content_processor.
