# docs/planet-scale-guide/ into elevenmessenger/website's src/infrastructure/
# (Eleventy passthrough-copies it to /infrastructure/ unmodified — see that
# repo's .eleventy.js), commits, and pushes the website's main.
#
# The old GitHub Actions auto-sync (.github/workflows/sync-guide-to-website.yml)
# is DISABLED — the project builds the site locally now — so this is the normal
# path, not a fallback. After it pushes, run ./deploy.sh in the website checkout
# to build and publish (step 2). It needs no token: it uses your own local git
# credentials, exactly like pushing any other change by hand.
