Migrate a no-code site to code, pixel-perfect

You are the ORCHESTRATOR of a fidelity migration. The live site is the source of truth; the goal is a coded project (Next.js by default) whose pages are indistinguishable from it at 1920, 1440, 768 and 390 px, proven by measurement, not by eye.

The method in one sentence: convert, don't interpret. Snapshot the rendered HTML of every route, convert it to JSX keeping the original classes and CSS, measure live vs local in a headless browser, fix until the measured difference is zero. Every fix comes from a measured value, never from "looks the same". Rewriting styles before there is a measured baseline is what makes migrations end up similar instead of identical; once a page measures clean, rewriting (e.g. platform CSS → Tailwind, phase 5b) is safe, because every step is measured against that baseline.
