Anonymous HTML was sent with 'public, max-age=60, s-maxage=300,
stale-while-revalidate=300'. After a rebuild the old chunk URLs (keyed by
deploy id) are deleted, so any browser/CDN holding the stale HTML got 404s
for up to five minutes. Since the deploy id is the git commit, the HTML must
be re-fetched after every deploy; only content-hashed static assets should
be cached. Return no-store for all HTML documents.
