Converts a Webflow HTML export into a maintainable React app with TanStack Start (SSR, TanStack Router conventions) using an idiomatic React-first approach. Sets up Storybook early, builds UI primitive + page-section SOT components with variant stories before composing routes. Use when the user has a Webflow export…

Keep GSAP animations from Webflow intact; initialize in useEffect with proper cleanup.

Global-effect hooks belong in MarketingSiteRoot, not scattered across sections.

Netlify + TanStack Start — netlify.toml at repo root with [build] base; MISSION CRITICAL — dashboard Build settings (Base, Publish, Build command, Functions directory, etc.) must stay empty or deploys break.

Netlify (and most CI) runs npm ci in web/ when web/package-lock.json exists. npm ci installs exactly what the lockfile pins — not “whatever npm install resolves today”.

Core Web Vitals — font preload, deferred analytics, optional CLS overrides, LCP images; expectations for render-blocking CSS on Webflow migrations.

SOT component CSS ownership — Storybook preview must match live routes without per-page token overrides.

Repeating UI chrome (buttons, headings, chips) — one SOT + variant Storybook stories before routes.

Self-hosted fonts in Vite/TanStack Start — file location, @font-face import order, Webflow legacy family names.

Netlify SSR (TanStack Start) — fix Cannot use import statement outside a module / ERRREQUIREESM by adding the offending package to ssr.noExternal in web/vite.config.ts. Always run the SSR import smoke test before pushing.

After Webflow → React migration, drop editor-only HTML fingerprints and fix generator/OG URLs so stack scanners (Wappalyzer, BuiltWith) do not falsely imply the site is still “hosted on Webflow”.

Keep Webflow class names and compiled CSS verbatim during migration; don't refactor to Tailwind utilities until visual parity is confirmed.

Floating widgets with iframes — z-index doesn't work, reserve layout space instead.
