Typography
Each font links to its Google Fonts page where available.
Not found on Google Fonts? Agent Instructions that you can follow if you have permission to use the fonts: CharacterQuilt.com suggests this flow that can help: 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 (pricing, blog, careers) — some weights only load on specific routes. 4. For each captured font URL: right-click → Save As to download the file locally. 5. View the page's CSS (DevTools → Sources, or curl the stylesheet URLs) and copy out the matching @font-face declarations. Rewrite each `src: url(...)` to point to your local file path. Programmatic alternative: load the URL with Playwright or Puppeteer, listen for `response` events whose `Content-Type` starts with `font/`, and write the body to disk. The CSS extraction step is the same. Only do this if you have permission to use the brand assets — most proprietary fonts are licensed and may not be redistributable.
