The CSSX persistence after SPA navigation is a client-side issue.
The boot.sx flush added collected-rules-to-head after island hydration,
but this may interfere with the morph/reactive rendering pipeline.
The client-side CSSX persistence fix needs to work with the DOM adapter's
scope mechanism (CEK frames), not the hashtable-based scope-emit!/scope-emitted
used by the server adapter. WASM will unify these — same evaluator on both sides.
