+# Build the Quarto docs site in docs/ and publish it to GitHub
+# Pages. Same pattern as sciSpatialR's pkgdown workflow.
+#
+# The site is rebuilt from docs/ on every run and handed to Pages
+# as a build artifact, so no rendered HTML is ever committed and
+# there is no gh-pages branch to keep in sync. Pull requests build
+# but do not publish, which surfaces a broken page during review
+# rather than after merge.
+#
+# The pages are plain Markdown, so Quarto renders them without R.
+# Which pages are built is set by `project: render` in
+# docs/_quarto.yml.
+#
+# Repository prerequisite: Settings > Pages > Source = "GitHub
+# Actions". Without that, the deploy job fails with a 404.
