Router-Links (z. B. React Router auf webklar.com) verhindern den Standard-Klick, dann griff onLinkClick nicht und das en der vorigen Seite ging verloren. Jetzt sendet der Seitenwechsel-Timer zuerst en (nur mit Einwilligung, einmal je Seite) und dann das pv der neuen Seite. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
