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": "GeistSans", "role": "body" }, { "family": "Geist", "role": "heading" }, { "family": "Arial", "role": "unknown" } ], "colors": { "primary": "#FDE3E3", "secondary": "#008FE9", "accent": "#85E5C2", "background": "#FFFFFF", "textPrimary": "#09090B", "link": "#85E5C2" }, "typography": { "fontFamilies": { "primary": "GeistSans", "heading": "Geist" }, "fontStacks": { "heading": [ "Geist", "ui-monospace", "SFMono-Regular", "Roboto Mono", "Menlo", "Monaco", "Liberation Mono", "DejaVu Sans Mono", "Courier New", "monospace" ], "body": [ "GeistSans", "Geist", "Arial", "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol" ], "paragraph": [ "GeistSans", "Geist", "Arial", "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol" ] }, "fontSizes": { "h1": "52px", "h2": "36px", "body": "17px" } }, "spacing": { "baseUnit": 4, "borderRadius": "6px" }, "components": { "buttonPrimary": { "background": "#FFFFFF", "textColor": "#FFFFFF", "borderColor": "#FFFFFF", "borderRadius": "9999px", "borderRadiusCorners": { "topLeft": "9999px", "topRight": "9999px", "bottomRight": "9999px", "bottomLeft": "9999px" }, "shadow": "none" }, "buttonSecondary": { "background": "transparent", "textColor": "#FFFFFF", "borderColor": "#FFFFFF", "borderRadius": "10px", "borderRadiusCorners": { "topLeft": "10px", "topRight": "10px", "bottomRight": "10px", "bottomLeft": "10px" }, "shadow": "none" } }, "images": { "logo": "data:image/svg+xml;utf8,%3Csvg%20width%3D%22100%25%22%20height%3D%22100%25%22%20viewBox%3D%220%200%20400%20400%22%20fill%3D%22none%22%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20aria-label%3D%2221st%20logo%22%20data-fc-idx%3D%220%22%3E%3Cpath%20fill-rule%3D%22evenodd%22%20clip-rule%3D%22evenodd%22%20d%3D%22M358.333%200C381.345%200%20400%2018.6548%20400%2041.6667V295.833C400%20298.135%20398.134%20300%20395.833%20300H270.833C268.532%20300%20266.667%20301.865%20266.667%20304.167V395.833C266.667%20398.134%20264.801%20400%20262.5%20400H41.6667C18.6548%20400%200%20381.345%200%20358.333V304.72C0%20301.793%201.54269%20299.081%204.05273%20297.575L153.76%20207.747C157.159%20205.708%20156.02%20200.679%20152.376%20200.065L151.628%20200H4.16667C1.86548%20200%206.71103e-08%20198.135%200%20195.833V104.167C1.07376e-06%20101.865%201.86548%20100%204.16667%20100H162.5C164.801%20100%20166.667%2098.1345%20166.667%2095.8333V4.16667C166.667%201.86548%20168.532%201.00666e-07%20170.833%200H358.333ZM170.833%20100C168.532%20100%20166.667%20101.865%20166.667%20104.167V295.833C166.667%20298.135%20168.532%20300%20170.833%20300H262.5C264.801%20300%20266.667%20298.135%20266.667%20295.833V104.167C266.667%20101.865%20264.801%20100%20262.5%20100H170.833Z%22%20fill%3D%22white%22%20style%3D%22fill%3A%20rgb(255%2C%20255%2C%20255)%20!important%3B%22%2F%3E%3C%2Fsvg%3E", "favicon": "https://1code.dev/favicon.ico", "ogImage": "https://21st.dev/og-agents.png", "logoAlt": "21st logo" }, "__llm_logo_reasoning": { "selectedIndex": 0, "reasoning": "Selected #0 because it is located in the header, visible, and matches the brand name '21st' from the alt text.", "confidence": 0.8, "source": "llm" }, "__llm_button_reasoning": { "primary": { "index": 2, "text": "Start on Web", "reasoning": "Button #2 'Start on Web' is likely the primary CTA due to its action-oriented text and distinct rounded design, suggesting a primary action." }, "secondary": { "index": 0, "text": "Subscribe", "reasoning": "Button #0 'Subscribe' is selected as secondary due to its transparent background, making it less prominent than the primary CTA." }, "confidence": 0.9 }, "personality": { "tone": "modern", "energy": "medium", "targetAudience": "developers and tech enthusiasts" }, "designSystem": { "framework": "tailwind", "componentLibrary": "" }, "confidence": { "buttons": 0.9, "colors": 0.9, "overall": 0.9 }, "__llm_metadata": { "logoSelection": { "llmCalled": true, "llmSucceeded": true, "finalSource": "llm", "rawLogoSelection": { "selectedLogoIndex": 0, "selectedLogoReasoning": "Selected #0 because it is located in the header, visible, and matches the brand name '21st' from the alt text.", "confidence": 0.8 } }, "buttonClassification": { "llmCalled": true, "llmSucceeded": true } } } ```
