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.
