Three end-to-end scenarios against a static+SSR test server: the zero-build page (import map + native ESM, no bundler), the SSR page (rendered content in the raw response, live after hydration, no mismatch warnings), and adoption (an expando on the server-rendered node survives a real render). Renders are raf-batched so assertions poll. Real Chromium flushed out three fixes happy-dom couldn't see: - nanoraf called an extracted requestAnimationFrame bare — Illegal invocation under strict-mode ESM (sloppy CJS had masked it); wrapped. - the counter example only routed '/', so serving it from any subpath threw; it now has a wildcard fallback. - hydration mismatch detection is now whitespace-insensitive (the parser reparents whitespace, e.g. text after </body>), and page scripts belong in <head> when a view owns <body> — same convention bankai v9 used. CI gets an e2e job with chromium-headless-shell. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014NgfSjHE11oFpoSnLVKLXd
