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.\n\nProgrammatic 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.\n\nOnly do this if you have permission to use the brand assets — most proprietary fonts are licensed and may not be redistributable.\n\n## Machine-Readable Profile\n\n```json\n{\n  \"colorScheme\": \"light\",\n  \"fonts\": [\n    {\n      \"family\": \"Inter\",\n      \"role\": \"body\"\n    },\n    {\n      \"family\": \"IBM Plex Mono\",\n      \"role\": \"monospace\"\n    }\n  ],\n  \"colors\": {\n    \"primary\": \"#151E3D\",\n    \"secondary\": \"#6E56CF\",\n    \"accent\": \"#6E56CF\",\n    \"background\": \"#FAFAFA\",\n    \"textPrimary\": \"#2B2B2B\",\n    \"link\": \"#1A1238\"\n  },\n  \"typography\": {\n    \"fontFamilies\": {\n      \"primary\": \"Inter\",\n      \"heading\": \"Inter\"\n    },\n    \"fontStacks\": {\n      \"heading\": [\n        \"Inter\",\n        \"Arial\",\n        \"sans-serif\"\n      ],\n      \"body\": [\n        \"Inter\",\n        \"Arial\",\n        \"sans-serif\"\n      ],\n      \"paragraph\": [\n        \"Inter\",\n        \"Arial\",\n        \"sans-serif\"\n      ]\n    },\n    \"fontSizes\": {\n      \"h1\": \"68px\",\n      \"h2\": \"18px\",\n      \"body\": \"18px\"\n    }\n  },\n  \"spacing\": {\n    \"baseUnit\": 4,\n    \"borderRadius\": \"8px\"\n  },\n  \"components\": {\n    \"input\": {\n      \"background\": \"transparent\",\n      \"textColor\": \"#151E3D\",\n      \"borderColor\": \"#BDBDCE\",\n      \"borderRadius\": \"8px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"8px\",\n        \"topRight\": \"8px\",\n        \"bottomRight\": \"8px\",\n        \"bottomLeft\": \"8px\"\n      },\n      \"shadow\": \"none\"\n    },\n    \"buttonPrimary\": {\n      \"background\": \"#6E56CF\",\n      \"textColor\": \"#FFFFFF\",\n      \"borderColor\": \"#6E56CF\",\n      \"borderRadius\": \"8px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"8px\",\n        \"topRight\": \"8px\",\n        \"bottomRight\": \"8px\",\n        \"bottomLeft\": \"8px\"\n      },\n      \"shadow\": \"none\"\n    },\n    \"buttonSecondary\": {\n      \"background\": \"#151E3D\",\n      \"textColor\": \"#FFFFFF\",\n      \"borderRadius\": \"0px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"0px\",\n        \"topRight\": \"0px\",\n        \"bottomRight\": \"0px\",\n        \"bottomLeft\": \"0px\"\n      },\n      \"shadow\": \"none\"\n    }\n  },\n  \"images\": {\n    \"logo\": \"https://cdn.prod.website-files.com/6978e7d86b5629eb801262d8/699c0f94ac35cdac38fc369a_Group%208.svg\",\n    \"favicon\": \"https://cdn.prod.website-files.com/6978e7d86b5629eb801262d8/6978fcf7c8dd61d29897f0ef_designHere.png\",\n    \"ogImage\": \"https://cdn.prod.website-files.com/6978e7d86b5629eb801262d8/69e8ef0398f9f48d56a37666_11.png\",\n    \"logoHref\": \"/\",\n    \"logoAlt\": \"Logo, click to go to home page.\"\n  },\n  \"__llm_logo_reasoning\": {\n    \"selectedIndex\": 0,\n    \"reasoning\": \"Selected #0 because it is visible, located in the header, links to the homepage, and matches the brand name 'GrowthBook'.\",\n    \"confidence\": 0.9,\n    \"source\": \"llm\"\n  },\n  \"__llm_button_reasoning\": {\n    \"primary\": {\n      \"index\": 6,\n      \"text\": \"Start for Free\",\n      \"reasoning\": \"Button #8 'Start for Free' uses a vibrant blue color (#6E56CF) and has action-oriented text, making it a strong primary CTA.\"\n    },\n    \"secondary\": {\n      \"index\": 4,\n      \"text\": \"Get StartedBook a Demo\",\n      \"reasoning\": \"Button #0 'Get StartedBook a Demo' uses a different color (#151E3D) and offers an alternative action, making it suitable as a secondary CTA.\"\n    },\n    \"confidence\": 0.95\n  },\n  \"personality\": {\n    \"tone\": \"professional\",\n    \"energy\": \"medium\",\n    \"targetAudience\": \"product managers, developers, data analysts\"\n  },\n  \"designSystem\": {\n    \"framework\": \"custom\",\n    \"componentLibrary\": \"\"\n  },\n  \"confidence\": {\n    \"buttons\": 0.95,\n    \"colors\": 0.9,\n    \"overall\": 0.925\n  },\n  \"__llm_metadata\": {\n    \"logoSelection\": {\n      \"llmCalled\": true,\n      \"llmSucceeded\": true,\n      \"finalSource\": \"llm\",\n      \"rawLogoSelection\": {\n        \"selectedLogoIndex\": 0,\n        \"selectedLogoReasoning\": \"Selected #0 because it is visible, located in the header, links to the homepage, and matches the brand name 'GrowthBook'.\",\n        \"confidence\": 0.9\n      }\n    },\n    \"buttonClassification\": {\n      \"llmCalled\": true,\n      \"llmSucceeded\": true\n    }\n  }\n}\n```\n"
