# Rendered by Jekyll on every build, so a new post or page appears here without
# anyone remembering to regenerate anything.
#
# jekyll-sitemap is not used because it emits no <lastmod> for pages and cannot
# emit <xhtml:link> hreflang alternates. Both come from front matter that
# tools/build.mjs writes into each generated page, and its validation pass
# fails the build if a page that should carry them does not.
#
# A page opts out with `sitemap: false` or `noindex: true`.
