# content_processor — local installation wrapper

# Generates content indexes (index.json + per-post html/json + filter indexes)
# from a site's markdown under site/content/, written to site/public/r — the real
# tree distro.ncl packs to the PV, which the pod's site/r symlink serves.
#
# Installed at $HOME/.local/bin/content_processor by `just local-install`.
#
# Site root resolution (same as rustelo-htmx-server):
#   1. --site <path>   explicit workspace root containing site/
#   2. $PWD has a site/ subdirectory
#   3. $HOME/.config/rustelo-htmx-server/ has site/
#
# All remaining args are forwarded to the real binary
# (e.g. --content-type blog, --language en, --watch).
