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\": \"Neufile Grotesk Extended\",\n      \"role\": \"heading\"\n    },\n    {\n      \"family\": \"Arial\",\n      \"role\": \"body\"\n    }\n  ],\n  \"colors\": {\n    \"primary\": \"#536EFF\",\n    \"secondary\": \"#FCEDE1\",\n    \"accent\": \"#186F64\",\n    \"background\": \"#FFFFFF\",\n    \"textPrimary\": \"#186F64\",\n    \"link\": \"#186F64\"\n  },\n  \"typography\": {\n    \"fontFamilies\": {\n      \"primary\": \"Arial\",\n      \"heading\": \"Neufile Grotesk Extended\"\n    },\n    \"fontStacks\": {\n      \"heading\": [\n        \"Albra Sans\",\n        \"-apple-system\",\n        \"BlinkMacSystemFont\",\n        \"Segoe UI\",\n        \"Helvetica\",\n        \"Apple Color Emoji\",\n        \"Arial\",\n        \"sans-serif\",\n        \"Segoe UI Emoji\",\n        \"Segoe UI Symbol\"\n      ],\n      \"body\": [\n        \"Neufile Grotesk Extended\",\n        \"-apple-system\",\n        \"BlinkMacSystemFont\",\n        \"Segoe UI\",\n        \"Helvetica\",\n        \"Apple Color Emoji\",\n        \"Arial\",\n        \"sans-serif\",\n        \"Segoe UI Emoji\",\n        \"Segoe UI Symbol\"\n      ],\n      \"paragraph\": [\n        \"Neufile Grotesk Extended\",\n        \"-apple-system\",\n        \"BlinkMacSystemFont\",\n        \"Segoe UI\",\n        \"Helvetica\",\n        \"Apple Color Emoji\",\n        \"Arial\",\n        \"sans-serif\",\n        \"Segoe UI Emoji\",\n        \"Segoe UI Symbol\"\n      ]\n    },\n    \"fontSizes\": {\n      \"h1\": \"80px\",\n      \"h2\": \"46px\",\n      \"body\": \"28px\"\n    }\n  },\n  \"spacing\": {\n    \"baseUnit\": 4,\n    \"borderRadius\": \"0px\"\n  },\n  \"components\": {\n    \"buttonPrimary\": {\n      \"background\": \"#644BC4\",\n      \"textColor\": \"#E6DEF0\",\n      \"borderRadius\": \"2px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"2px\",\n        \"topRight\": \"2px\",\n        \"bottomRight\": \"2px\",\n        \"bottomLeft\": \"2px\"\n      },\n      \"shadow\": \"none\"\n    },\n    \"buttonSecondary\": {\n      \"background\": \"#154EA5\",\n      \"textColor\": \"#E6EBEC\",\n      \"borderRadius\": \"2px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"2px\",\n        \"topRight\": \"2px\",\n        \"bottomRight\": \"2px\",\n        \"bottomLeft\": \"2px\"\n      },\n      \"shadow\": \"none\"\n    }\n  },\n  \"images\": {\n    \"logo\": \"data:image/svg+xml;utf8,%3Csvg%20width%3D%2225%22%20height%3D%2228%22%20viewBox%3D%220%200%2025%2028%22%20fill%3D%22none%22%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20data-fc-idx%3D%220%22%3E%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%3Cpath%20d%3D%22M8.4061%2017.0592H4.98217C1.18173%2017.0592%20-0.865569%2012.588%201.61707%209.69756L9.93569%200H23.0431L8.4061%2017.0592Z%22%20style%3D%22fill%3A%20rgb(25%2C%2027%2C%2031)%20!important%3B%22%2F%3E%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%3Cpath%20d%3D%22M8.40625%2017.0593L6.20599%2019.643C3.73512%2022.5334%205.78242%2027.0046%209.58286%2027.0046H15.9836L24.4669%2017.0711H8.40625V17.0593Z%22%20style%3D%22fill%3A%20rgb(25%2C%2027%2C%2031)%20!important%3B%22%2F%3E%0A%20%20%20%20%20%20%20%20%20%20%20%20%3C%2Fsvg%3E\",\n    \"favicon\": \"https://letter.co/static/apple-touch-icon.png\",\n    \"ogImage\": \"https://letter.co/static/fb-share.jpg\",\n    \"logoHref\": \"/\"\n  },\n  \"__llm_logo_reasoning\": {\n    \"selectedIndex\": 0,\n    \"reasoning\": \"Selected #0 because it is located in the header, is visible, and links to the homepage, matching the brand 'Letter'.\",\n    \"confidence\": 0.9,\n    \"source\": \"llm\"\n  },\n  \"__llm_button_reasoning\": {\n    \"primary\": {\n      \"index\": 1,\n      \"text\": \"Start Lending\",\n      \"reasoning\": \"Button #7 with text 'Start Lending' uses a vibrant blue color (#644BC4) which stands out as a primary call-to-action.
