  // The fonts are self-hosted (scss/global/_fonts.scss), so nothing here talks to
  // fonts.googleapis.com any more. What is left is a preload for the two files first paint
  // actually needs — body regular and the title weight, latin subset. The @font-face rules
  // live inside the render-blocking bundle, so without these the browser cannot even ask for
  // a glyph until the CSS is parsed. latin-ext is deliberately not preloaded: its
  // `unicode-range` means it is only fetched when a page really uses those codepoints.
  // `crossorigin` is not optional even same-origin — fonts are always fetched in CORS mode,
  // and a preload without it is a second, wasted request.
