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. ## Machine-Readable Profile ```json { "colorScheme": "light", "fonts": [ { "family": "Neufile Grotesk Extended", "role": "heading" }, { "family": "Arial", "role": "body" } ], "colors": { "primary": "#536EFF", "secondary": "#FCEDE1", "accent": "#186F64", "background": "#FFFFFF", "textPrimary": "#186F64", "link": "#186F64" }, "typography": { "fontFamilies": { "primary": "Arial", "heading": "Neufile Grotesk Extended" }, "fontStacks": { "heading": [ "Albra Sans", "-apple-system", "BlinkMacSystemFont", "Segoe UI", "Helvetica", "Apple Color Emoji", "Arial", "sans-serif", "Segoe UI Emoji", "Segoe UI Symbol" ], "body": [ "Neufile Grotesk Extended", "-apple-system", "BlinkMacSystemFont", "Segoe UI", "Helvetica", "Apple Color Emoji", "Arial", "sans-serif", "Segoe UI Emoji", "Segoe UI Symbol" ], "paragraph": [ "Neufile Grotesk Extended", "-apple-system", "BlinkMacSystemFont", "Segoe UI", "Helvetica", "Apple Color Emoji", "Arial", "sans-serif", "Segoe UI Emoji", "Segoe UI Symbol" ] }, "fontSizes": { "h1": "80px", "h2": "46px", "body": "28px" } }, "spacing": { "baseUnit": 4, "borderRadius": "0px" }, "components": { "buttonPrimary": { "background": "#644BC4", "textColor": "#E6DEF0", "borderRadius": "2px", "borderRadiusCorners": { "topLeft": "2px", "topRight": "2px", "bottomRight": "2px", "bottomLeft": "2px" }, "shadow": "none" }, "buttonSecondary": { "background": "#154EA5", "textColor": "#E6EBEC", "borderRadius": "2px", "borderRadiusCorners": { "topLeft": "2px", "topRight": "2px", "bottomRight": "2px", "bottomLeft": "2px" }, "shadow": "none" } }, "images": { "logo": "data:image/svg+xml;utf8,%3Csvg%20width%3D%2225%22%20height%3D%2228%22%20viewBox%3D%220%200%2025%2028%22%20fill%3D%22none%22%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20data-fc-idx%3D%220%22%3E%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%3Cpath%20d%3D%22M8.4061%2017.0592H4.98217C1.18173%2017.0592%20-0.865569%2012.588%201.61707%209.69756L9.93569%200H23.0431L8.4061%2017.0592Z%22%20style%3D%22fill%3A%20rgb(25%2C%2027%2C%2031)%20!important%3B%22%2F%3E%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%3Cpath%20d%3D%22M8.40625%2017.0593L6.20599%2019.643C3.73512%2022.5334%205.78242%2027.0046%209.58286%2027.0046H15.9836L24.4669%2017.0711H8.40625V17.0593Z%22%20style%3D%22fill%3A%20rgb(25%2C%2027%2C%2031)%20!important%3B%22%2F%3E%0A%20%20%20%20%20%20%20%20%20%20%20%20%3C%2Fsvg%3E", "favicon": "https://letter.co/static/apple-touch-icon.png", "ogImage": "https://letter.co/static/fb-share.jpg", "logoHref": "/" }, "__llm_logo_reasoning": { "selectedIndex": 0, "reasoning": "Selected #0 because it is located in the header, is visible, and links to the homepage, matching the brand 'Letter'.", "confidence": 0.9, "source": "llm" }, "__llm_button_reasoning": { "primary": { "index": 1, "text": "Start Lending", "reasoning": "Button #7 with text 'Start Lending' uses a vibrant blue color (#644BC4) which stands out as a primary call-to-action.
