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": "IBM Plex Mono", "role": "monospace" }, { "family": "IBM Plex Sans", "role": "body" } ], "colors": { "primary": "#F0FB29", "secondary": "#AEE3FD", "accent": "#F0FB29", "background": "#F5F5F5", "textPrimary": "#202020", "link": "#3898EC" }, "typography": { "fontFamilies": { "primary": "IBM Plex Sans", "heading": "IBM Plex Sans" }, "fontStacks": { "heading": [ "Arial", "Helvetica Neue", "Helvetica", "sans-serif" ], "body": [ "Arial", "Helvetica Neue", "Helvetica", "sans-serif" ], "paragraph": [ "Arial", "Helvetica Neue", "Helvetica", "sans-serif" ] }, "fontSizes": { "h1": "14px", "h2": "64px", "body": "14px" } }, "spacing": { "baseUnit": 4, "borderRadius": "40px" }, "components": { "input": { "background": "transparent", "textColor": "#202020", "borderColor": "#202020", "borderRadius": "0px", "borderRadiusCorners": { "topLeft": "0px", "topRight": "0px", "bottomRight": "0px", "bottomLeft": "0px" }, "shadow": "none" }, "buttonPrimary": { "background": "#F0FB29", "textColor": "#333333", "borderRadius": "0px", "borderRadiusCorners": { "topLeft": "0px", "topRight": "0px", "bottomRight": "0px", "bottomLeft": "0px" }, "shadow": "none" }, "buttonSecondary": { "background": "#202020", "textColor": "#F0FB29", "borderRadius": "100px", "borderRadiusCorners": { "topLeft": "100px", "topRight": "100px", "bottomRight": "100px", "bottomLeft": "100px" }, "shadow": "none" } }, "images": { "logo": "https://cdn.prod.website-files.com/681bfb0c9a4601bc6e288ec4/683ca847da3bc476a2729c70_f5d2bfe3617d9aff82a3e717fb2ed0ba_logo-bracksmith-icon-light.svg", "favicon": "https://cdn.prod.website-files.com/681bfb0c9a4601bc6e288ec4/684a16c003e68ef866f5f528_logo-blacksmith-favicon-light.png", "ogImage": "https://cdn.prod.website-files.com/681bfb0c9a4601bc6e288ec4/684b4a332c1905034fdee368_ebf0b394c307e7e092874768e7f43edc_image-sblacksmith-socialgraph.png" }, "__llm_logo_reasoning": { "selectedIndex": 0, "reasoning": "Logo rejected: Red flags detected (menu word).
