Server pages legitimately carry scripts (state serialization, analytics)
that are spent by hydration time and that client views never render —
they are noise to the detector, and morph dropping them is harmless.

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.

hydrate(oldNode, newNode) normalizes the client tree to parser text-node
granularity, walks both trees to report the first server/client markup
disagreement (node, text, attribute, or child count, with a path), then
morphs — matching nodes are adopted in place, the client render wins.
choo.mount() now hydrates and console.warns on mismatch.
Building this surfaced two real isomorphism divergences, both fixed:
adjacent text nodes from template holes vs the parser's merged runs
(folded via Node.normalize), and the server serializing onclick="" where
the browser sets a property — event handlers now leave no trace in server
markup at all.
