  One stylesheet, no build step.

  This site exists to be live on a real domain quickly: Google will not verify the YouTube
  scopes against localhost, and a privacy policy that is not published is not a policy. Flat
  HTML deploys to GitHub Pages straight from the repository, so connecting a domain is a DNS
  record rather than a pipeline.
