Website Design Style Extractor

Render one public page in Chromium without AI. Choose desktop (1440 × 1000) or mobile (390 × 844), light or dark preference, and an extra wait of 0–3000 ms. ZIP includes design.md, screenshot.png, tokens.json and tokens.css; Markdown embeds the PNG for a self-contained document.

The screenshot covers the fixed viewport. Style observations sample up to 1000 visible rendered elements in a scan of at most 2000 DOM elements, including below-fold elements; there is no automatic scrolling. Colors, CSS font stacks, spacing, borders, radii, shadows, components and readable custom properties are observations, not the original design system. Font stacks do not prove which font actually rendered. Frequency counts describe sampled CSS declarations, not painted area, brand roles or accessibility compliance.

Only public HTTP on port 80 and HTTPS on port 443 are allowed, without URL credentials. Capture is capped at 40 seconds, 30 MiB of network traffic and 200 requests, with an 8 MiB limit per HTML document; blocked resources or sampling limits can reduce coverage. The capture sandbox disables popups, form submissions, downloads, WebSocket connections and background workers; content depending on these features may differ from a normal browser. No login, cookie acceptance, CAPTCHA solving, clicking or cross-origin frame inspection. Use the built-in demo for a real offline Chromium extraction with all networking blocked.
