I haven’t got round to publishing them properly (z = fast-forward in particular I have in mind to write a blog post about, on how to write user scripts for things you want), but the fast-forward one is at https://temp.chrismorgan.info/z%20=%20%E2%8F%A9.user.js. For the Cloudflare one, I won’t list its full source, but it’s this:

  if (document.querySelector("script[src$='/cloudflare-static/email-decode.min.js']")) {
      {The source of that JavaScript file, minus the “remove the email-decode.min.js script tag” thing.}
  }
