Answers a request through spool when it applies, and through the page pipeline alone otherwise.
Spool answers /spool-sw.js and /.spool/* itself, decorates an eligible page so a device can
keep it, converts an image the browser can take as WebP, and rewrites a page's video tags and
embeds. The pipeline runs underneath unchanged, so every cache tier is the one a visitor met
before spool existed and no stored page is a decorated one.
