Decides whether html may use the trimmed stylesheets it links. It may not when one of its
tokens is in a linked entry's missing set, or when it loads a same-origin script the manifest
was not built with. Then each link to a trimmed file gets spool-trim=0, which the proxy
answers with the full file. It cannot see a class a third-party script adds, or markup injected
after load from a page the manifest never covered.
