# Publish this repo's static HTML to https://pages.rootiest.dev/<repo>/.
#
# Runs on Gitea only: the racknerd runner's "pages" label is a container job
# that may mount the Caddy web root (~/docker/caddy/pages, the runner's only
# valid_volumes entry). Gitea mirrors this repo to GitHub, which also sees
# this file, so the job is skipped there; a skipped job costs nothing and
# leaves no pending status.
#
# To publish more files, add "source destination" lines to PAGES. The
# destination is relative to pages.rootiest.dev/<repo>/; anything under a
# private/ directory needs a Rootiest ID login.
