Why "convert this website to React" is so painful and how I automated 80% of it

Short summary

A developer automated website-to-React conversion by rendering in headless browsers, reading computed styles, and reconstructing components. The tool achieves ~80% automation on clean sites with Tailwind mapping. Output is a runnable Next.js project ready for developer refinement, not pixel-perfect.

• •Renders pages in headless browsers and extracts computed styles instead of parsing CSS cascades
• •Reconstructs component structure from DOM and maps visual values to Tailwind utilities
• •Achieves 80% automation on clean sites; struggles with canvas/WebGL and complex animations
