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 Sans\",\n      \"role\": \"body\"\n    },\n    {\n      \"family\": \"Ubuntu\",\n      \"role\": \"unknown\"\n    }\n  ],\n  \"colors\": {\n    \"primary\": \"#E1D7C2\",\n    \"secondary\": \"#F5E2B2\",\n    \"accent\": \"#CD8407\",\n    \"background\": \"#E1D7C2\",\n    \"textPrimary\": \"#4D4F46\",\n    \"link\": \"#E3DFD1\"\n  },\n  \"typography\": {\n    \"fontFamilies\": {\n      \"primary\": \"IBM Plex Sans\",\n      \"heading\": \"IBM Plex Sans\"\n    },\n    \"fontStacks\": {\n      \"heading\": [\n        \"IBM Plex Sans\",\n        \"-apple-system\",\n        \"BlinkMacSystemFont\",\n        \"avenir next\",\n        \"avenir\",\n        \"segoe ui\",\n        \"helvetica neue\",\n        \"helvetica\",\n        \"Ubuntu\",\n        \"roboto\",\n        \"noto\",\n        \"arial\",\n        \"sans-serif\"\n      ],\n      \"body\": [\n        \"IBM Plex Sans\",\n        \"-apple-system\",\n        \"BlinkMacSystemFont\",\n        \"avenir next\",\n        \"avenir\",\n        \"segoe ui\",\n        \"helvetica neue\",\n        \"helvetica\",\n        \"Ubuntu\",\n        \"roboto\",\n        \"noto\",\n        \"arial\",\n        \"sans-serif\"\n      ],\n      \"paragraph\": [\n        \"IBM Plex Sans\",\n        \"-apple-system\",\n        \"BlinkMacSystemFont\",\n        \"avenir next\",\n        \"avenir\",\n        \"segoe ui\",\n        \"helvetica neue\",\n        \"helvetica\",\n        \"Ubuntu\",\n        \"roboto\",\n        \"noto\",\n        \"arial\",\n        \"sans-serif\"\n      ]\n    },\n    \"fontSizes\": {\n      \"h1\": \"16px\",\n      \"h2\": \"16px\",\n      \"body\": \"16px\"\n    }\n  },\n  \"spacing\": {\n    \"baseUnit\": 4,\n    \"borderRadius\": \"4px\"\n  },\n  \"components\": {\n    \"buttonPrimary\": {\n      \"background\": \"#CD8407\",\n      \"textColor\": \"#23251D\",\n      \"borderColor\": \"#B17816\",\n      \"borderRadius\": \"6px\",\n      \"borderRadiusCorners\": {\n        \"topLeft\": \"6px\",\n        \"topRight\": \"6px\",\n        \"bottomRight\": \"6px\",\n        \"bottomLeft\": \"6px\"\n      },\n      \"shadow\": \"none\"\n    }\n  },\n  \"images\": {\n    \"logo\": \"https://res.cloudinary.com/dmukukwp6/image/upload/doc_2fa451a8e4.png\",\n    \"favicon\": \"https://posthog.com/favicon-32x32.png?v=6e5ac8d4a5b381b5caa29396fbf7c955\",\n    \"ogImage\": \"https://posthog.com/images/og/default.png\",\n    \"logoHref\": \"/\"\n  },\n  \"__llm_logo_reasoning\": {\n    \"selectedIndex\": 0,\n    \"reasoning\": \"Selected #0 because it is located in the header, links to the homepage, and is visible.
