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": "dark", "fonts": [ { "family": "SF Pro Display", "role": "body" }, { "family": "SF Pro", "role": "body" }, { "family": "SF Mono", "role": "monospace" }, { "family": "Fira Code", "role": "monospace" }, { "family": "Segoe UI", "role": "body" } ], "colors": { "primary": "#71621B", "secondary": "#4A4014", "accent": "#F2CF2F", "background": "#08090A", "textPrimary": "#08090A", "link": "#F2CF2F" }, "typography": { "fontFamilies": { "primary": "SF Pro Display", "heading": "SF Pro Display" }, "fontStacks": { "heading": [ "-apple-system", "BlinkMacSystemFont", "SF Pro Display", "SF Pro", "Segoe UI", "system-ui", "sans-serif" ], "body": [ "-apple-system", "BlinkMacSystemFont", "SF Pro Display", "SF Pro", "Segoe UI", "system-ui", "sans-serif" ], "paragraph": [ "-apple-system", "BlinkMacSystemFont", "SF Pro Display", "SF Pro", "Segoe UI", "system-ui", "sans-serif" ] }, "fontSizes": { "h1": "60px", "h2": "60px", "body": "18px" } }, "spacing": { "baseUnit": 4, "borderRadius": "28px" }, "components": { "buttonPrimary": { "background": "#141515", "textColor": "#08090A", "borderColor": "#71621B", "borderRadius": "9999px", "borderRadiusCorners": { "topLeft": "9999px", "topRight": "9999px", "bottomRight": "9999px", "bottomLeft": "9999px" }, "shadow": "rgba(242, 207, 47, 0.18) 0px 18px 48px 0px" }, "buttonSecondary": { "background": "transparent", "textColor": "#08090A", "borderColor": "#71621B", "borderRadius": "9999px", "borderRadiusCorners": { "topLeft": "9999px", "topRight": "9999px", "bottomRight": "9999px", "bottomLeft": "9999px" }, "shadow": "rgba(242, 207, 47, 0.18) 0px 18px 48px 0px" } }, "images": { "logo": "data:image/svg+xml,%3csvg%20xmlns='http://www.w3.org/2000/svg'%20width='100%25'%20height='100%25'%20viewBox='0%200%2016%2016'%20role='img'%20aria-label='F4%20Logo'%3e%3c!--%20Simplified%20for%20QtSvg%20compatibility:%20use%206-digit%20hex%20colors%20(QtSvg%20may%20ignore%208-digit)%20--%3e%3ctitle%3eF4%20Logo%3c/title%3e%3cpath%20fill='%23ffffff'%20d='M5.879%208.83c.76%200%201.378.617%201.376%201.378l-.011%205.797H5.386V13.85a.43.43%200%200%200-.43-.43h-2.53v-1.525h2.537a.43.43%200%200%200%20.43-.431v-.724a.43.43%200%200%200-.43-.43H.002V8.83h5.877Zm10.142%201.48H11.06a.43.43%200%200%200-.43.43v.724c0%20.237.193.43.43.43h2.538v1.526h-2.53a.43.43%200%200%200-.43.43v2.155h-1.86l-.012-5.797a1.377%201.377%200%200%201%201.377-1.379h5.877v1.481Zm-5.385-8.15c0%20.238.194.43.431.43h2.53v1.525H11.06a.43.43%200%200%200-.43.43v.725c0%20.237.193.43.43.43h4.962v1.482h-5.877a1.377%201.377%200%200%201-1.377-1.38L8.78.005h1.857V2.16Zm-3.38%203.642A1.377%201.377%200%200%201%205.878%207.18H.002V5.699h4.962a.43.43%200%200%200%20.43-.43v-.723a.43.43%200%200%200-.43-.43h-2.54V2.59h2.53a.43.43%200%200%200%20.431-.43V.005h1.858l.011%205.797Z'/%3e%3c/svg%3e", "favicon": "https://f4.dev/favicon.svg", "ogImage": "https://f4.dev/social/og-default-1200x630.png", "logoHref": "/", "logoAlt": "F4" }, "__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 'F4 Industries'.", "confidence": 0.9, "source": "llm" }, "__llm_button_reasoning": { "primary": { "index": 1, "text": "Contact Sales", "reasoning": "Button #1 'Contact Sales' is marked as primary and has a distinct background color (#141515) with a border color matching the primary brand color (#71621B), indicating its importance as a CTA." }, "secondary": { "index": 5, "text": "Go to Downloads", "reasoning": "Button #5 'Go to Downloads' has a transparent background, making it a suitable secondary action with a different color group from the primary button." }, "confidence": 0.9 }, "personality": { "tone": "professional", "energy": "medium", "targetAudience": "engineers and technical professionals" }, "designSystem": { "framework": "custom", "componentLibrary": "" }, "confidence": { "buttons": 0.9, "colors": 0.95, "overall": 0.925 }, "__llm_metadata": { "logoSelection": { "llmCalled": true, "llmSucceeded": true, "finalSource": "llm", "rawLogoSelection": { "selectedLogoIndex": 0, "selectedLogoReasoning": "Selected #0 because it is located in the header, is visible, and links to the homepage, matching the brand 'F4 Industries'.", "confidence": 0.9 } }, "buttonClassification": { "llmCalled": true, "llmSucceeded": true } } } ```
