Working with these fonts

Not found on Google Fonts? Instructions for using the fonts:

  1. Open the company's homepage in a browser with DevTools open.
  2. In the Network tab, filter by "Font" (or by extension: woff2, woff, ttf, otf).
  3. Hard-reload the page and click around — some weights only load on specific routes.
  4. For each captured font URL: right-click → Save As to download locally.
  5. View the page's CSS and copy out matching @font-face declarations. Rewrite each src: url(...) to point to your local file path.
