September 2025 monthly summary for gravity-ui/page-constructor. Key delivery: NavigationLink OnClick handling bug fix. This change ensures the original onClick handler receives the event object and that the custom click logic runs after analytics events have been processed, improving reliability of user interactions and analytics data. Impact: reduced risk of click-event loss, more accurate analytics, and more predictable behavior for end users. Tech stack: React event handling, analytics integration, and a targeted rewrite of onClick logic. Commit reference: 166338fa47a3517a9ab09760c529040ea074a2fd, 'fix(NavigationLink): rewrite onClick (#1296)'.
