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\": \"Geist\",\n      \"role\": \"heading\"\n    },\n    {\n      \"family\": \"Arial\",\n      \"role\": \"body\"\n    },\n    {\n      \"family\": \"Inter\",\n      \"role\": \"unknown\"\n    }\n  ],\n  \"colors\": {\n    \"primary\": \"#3898EC\",\n    \"secondary\": \"#DC2626\",\n    \"accent\": \"#000000\",\n    \"background\": \"#FFFFFF\",\n    \"textPrimary\": \"#000000\",\n    \"link\": \"#64748B\"\n  },\n  \"typography\": {\n    \"fontFamilies\": {\n      \"primary\": \"Arial\",\n      \"heading\": \"Geist\"\n    },\n    \"fontStacks\": {\n      \"heading\": [\n        \"Geist\",\n        \"Arial\",\n        \"sans-serif\"\n      ],\n      \"body\": [\n        \"Geist\",\n        \"Arial\",\n        \"sans-serif\"\n      ],\n      \"paragraph\": [\n        \"Geist\",\n        \"Arial\",\n        \"sans-serif\"\n      ]\n    },\n    \"fontSizes\": {\n      \"h1\": \"56px\",\n      \"h2\": \"56px\",\n      \"body\": \"17px\"\n    }\n  },\n  \"spacing\": {\n    \"baseUnit\": 4,\n    \"borderRadius\": \"3px\"\n  },\n  \"components\": {\n    \"buttonPrimary\": {\n      \"background\": \"#000000\",\n      \"textColor\": \"#FFFFFF\",\n      \"borderRadius\": \"200px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"200px\",\n        \"topRight\": \"200px\",\n        \"bottomRight\": \"200px\",\n        \"bottomLeft\": \"200px\"\n      },\n      \"shadow\": \"none\"\n    },\n    \"buttonSecondary\": {\n      \"background\": \"#FFFFFF\",\n      \"textColor\": \"#000000\",\n      \"borderColor\": \"#E6E6E6\",\n      \"borderRadius\": \"200px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"200px\",\n        \"topRight\": \"200px\",\n        \"bottomRight\": \"200px\",\n        \"bottomLeft\": \"200px\"\n      },\n      \"shadow\": \"none\"\n    }\n  },\n  \"images\": {\n    \"logo\": \"https://cdn.prod.website-files.com/6943a12c7ff63aee4ba25b8b/6944589610adb84ab2e1c38a_logo.png\",\n    \"favicon\": \"https://cdn.prod.website-files.com/6943a12c7ff63aee4ba25b8b/696a7efb5b0c0091cb7f3dc5_favicon-32x32.png\",\n    \"ogImage\": \"https://cdn.prod.website-files.com/6943a12c7ff63aee4ba25b8b/698e176a4603133f9ff29193_97e3257b99ce02fc09b7c9f44f840874_og.png\",\n    \"logoHref\": \"/\",\n    \"logoAlt\": \"Logo Link that leads to home page\"\n  },\n  \"__llm_logo_reasoning\": {\n    \"selectedIndex\": 2,\n    \"reasoning\": \"Selected #0 because it is visible, located in the header, links to the homepage, and matches the brand name 'Substrate'.\",\n    \"confidence\": 0.95,\n    \"source\": \"llm\"\n  },\n  \"__llm_button_reasoning\": {\n    \"primary\": {\n      \"index\": 0,\n      \"text\": \"Book a DemoBook a Demo\",\n      \"reasoning\": \"Button #5 'Book a Demo' has a strong call-to-action text and uses a dark background color, making it stand out as a primary CTA.\"\n    },\n    \"secondary\": {\n      \"index\": 12,\n      \"text\": \"View Covered Payers →View Covered Payers →\",\n      \"reasoning\": \"Button #4 'View Covered Payers' has a different background color (#FFFFFF) and serves as a secondary action with informative text.\"\n    },\n    \"confidence\": 0.9\n  },\n  \"personality\": {\n    \"tone\": \"professional\",\n    \"energy\": \"medium\",\n    \"targetAudience\": \"healthcare professionals\"\n  },\n  \"designSystem\": {\n    \"framework\": \"custom\",\n    \"componentLibrary\": \"\"\n  },\n  \"confidence\": {\n    \"buttons\": 0.9,\n    \"colors\": 0.9,\n    \"overall\": 0.9\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 'Substrate'.\",\n        \"confidence\": 0.95\n      }\n    },\n    \"buttonClassification\": {\n      \"llmCalled\": true,\n      \"llmSucceeded\": true\n    }\n  }\n}\n```\n"
