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\": \"IBM Plex Mono\",\n      \"role\": \"monospace\"\n    },\n    {\n      \"family\": \"IBM Plex Sans\",\n      \"role\": \"body\"\n    }\n  ],\n  \"colors\": {\n    \"primary\": \"#F0FB29\",\n    \"secondary\": \"#AEE3FD\",\n    \"accent\": \"#F0FB29\",\n    \"background\": \"#F5F5F5\",\n    \"textPrimary\": \"#202020\",\n    \"link\": \"#3898EC\"\n  },\n  \"typography\": {\n    \"fontFamilies\": {\n      \"primary\": \"IBM Plex Sans\",\n      \"heading\": \"IBM Plex Sans\"\n    },\n    \"fontStacks\": {\n      \"heading\": [\n        \"Arial\",\n        \"Helvetica Neue\",\n        \"Helvetica\",\n        \"sans-serif\"\n      ],\n      \"body\": [\n        \"Arial\",\n        \"Helvetica Neue\",\n        \"Helvetica\",\n        \"sans-serif\"\n      ],\n      \"paragraph\": [\n        \"Arial\",\n        \"Helvetica Neue\",\n        \"Helvetica\",\n        \"sans-serif\"\n      ]\n    },\n    \"fontSizes\": {\n      \"h1\": \"14px\",\n      \"h2\": \"64px\",\n      \"body\": \"14px\"\n    }\n  },\n  \"spacing\": {\n    \"baseUnit\": 4,\n    \"borderRadius\": \"40px\"\n  },\n  \"components\": {\n    \"input\": {\n      \"background\": \"transparent\",\n      \"textColor\": \"#202020\",\n      \"borderColor\": \"#202020\",\n      \"borderRadius\": \"0px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"0px\",\n        \"topRight\": \"0px\",\n        \"bottomRight\": \"0px\",\n        \"bottomLeft\": \"0px\"\n      },\n      \"shadow\": \"none\"\n    },\n    \"buttonPrimary\": {\n      \"background\": \"#F0FB29\",\n      \"textColor\": \"#333333\",\n      \"borderRadius\": \"0px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"0px\",\n        \"topRight\": \"0px\",\n        \"bottomRight\": \"0px\",\n        \"bottomLeft\": \"0px\"\n      },\n      \"shadow\": \"none\"\n    },\n    \"buttonSecondary\": {\n      \"background\": \"#202020\",\n      \"textColor\": \"#F0FB29\",\n      \"borderRadius\": \"100px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"100px\",\n        \"topRight\": \"100px\",\n        \"bottomRight\": \"100px\",\n        \"bottomLeft\": \"100px\"\n      },\n      \"shadow\": \"none\"\n    }\n  },\n  \"images\": {\n    \"logo\": \"https://cdn.prod.website-files.com/681bfb0c9a4601bc6e288ec4/683ca847da3bc476a2729c70_f5d2bfe3617d9aff82a3e717fb2ed0ba_logo-bracksmith-icon-light.svg\",\n    \"favicon\": \"https://cdn.prod.website-files.com/681bfb0c9a4601bc6e288ec4/684a16c003e68ef866f5f528_logo-blacksmith-favicon-light.png\",\n    \"ogImage\": \"https://cdn.prod.website-files.com/681bfb0c9a4601bc6e288ec4/684b4a332c1905034fdee368_ebf0b394c307e7e092874768e7f43edc_image-sblacksmith-socialgraph.png\"\n  },\n  \"__llm_logo_reasoning\": {\n    \"selectedIndex\": 0,\n    \"reasoning\": \"Logo rejected: Red flags detected (menu word).
