The board rendered vertically for a user whose browser had cached the
pre-sectioning style.css: deploys overwrite /srv/homepage in place, and
nothing told the browser to revalidate. The @home handler on the post-auth
listener now sends Cache-Control: no-cache, so every load is an ETag
round-trip (a cheap 304 when unchanged) and a deploy is always visible on
the next navigation.
