Guide: Visual-First Web Cloning Recipe v2

When building a high-fidelity landing page clone, the biggest trap is relying purely on DOM trees and CSS dumps. Modern website builders (Framer, Webflow) generate deeply nested "div soup" and obfuscated CSS to create visual effects.

The Golden Rule: Trust your "eyes" (screenshots) first, but when an effect looks too complex to be pure CSS, use Deep DOM Interrogation to steal the exact asset — never guess the math.

Tool note: This guide uses AdaL browser-use agent tools (navigate, javascript_tool, computer, resize_window, tabs_context, bash). If you're not on AdaL, the same JS payloads work with Chrome DevTools MCP (evaluate_script), Playwright (page.evaluate), or any browser automation tool — just swap the invocation wrapper.

The 80/20 Cloning Philosophy

Divide your workflow into two phases so you don't get bogged down pixel-pushing too early:

1. The 80% Sprint (Speed & Structure): Get the page laid out rapidly. Fetch the semantic HTML, scaffold the React component tree (Navbar, Hero, Features), and apply basic Tailwind for layout (Flex/Grid) and spacing. Accept approximations — solid colors instead of gradients, standard shadows, static backgrounds. Move fast.
2. The 20% Polish (Pixel Perfection & Physics): Once the structure is on screen, shift to meticulous engineering. Use "Sniper CSS" to extract exact multi-stop gradients, rip WebGL canvas backgrounds to .webm, map massive multi-layer box-shadows, and implement Framer Motion spring physics.
