 * Called for every rendered element with its VNode. Known element types
 * arrive NORMALIZED (defaults filled) with any unrecognized ad-hoc keys
 * preserved; elements of unknown type (the editor's `registerShapeModel`
 * extensions) arrive verbatim and render as an empty placeholder unless the
 * hook returns a replacement. Return a replacement VNode — or a raw markup
 * string, which the serializers emit as-is (master hooks were untyped and
 * both are supported at runtime) — sync or async; any falsy return keeps
 * the original. Typed loosely because extension elements flow through —
 * known types match the schema `Element` union at runtime.
