UI Changes: - Removed purple gradient 'Add to Calendar' button from event detail hero section - Removed 'Save the Date' purple sidebar section from event detail page - Removed unused addToCalendar function and atcb_action import Performance Optimization: - Converted /events page from SSR (getServerSideProps) to SSG with ISR (getStaticProps with 10min revalidation) - This matches the homepage's static generation strategy for faster page loads

…tics - Remove AnnouncementBanner (was making blocking API call on every page load) - Remove Google Analytics - Defer PostHog initialization using requestIdleCallback (falls back to 2s timeout) - Add dynamic imports for below-the-fold landing page sections: - UpcomingEvents, UpcomingWorkshops, CommunityValues, Partners, JoinCTA These changes reduce blocking work on the main thread during initial page load.
- Update sanity, next-sanity, postcss, posthog-js packages - Add pnpm overrides to force patched versions of transitive dependencies: - undici >=7.29.0 (fixes cross-user info disclosure, CRLF injection) - dompurify >=3.4.13 (fixes XSS via IN_PLACE hook) - js-yaml >=4.3.1 (fixes quadratic CPU consumption) - nanoid >=3.3.18 (fixes infinite loop with zero size) - postcss >=8.5.23 (fixes arbitrary .map file reads) - brace-expansion 5.0.9 for versions >=4.0.0 (fixes DoS) - Remove deprecated brace-expansion patch (no longer needed) Audit now passes with no known vulnerabilities.

Constrain the global overrides to their intended major versions.
The lockfile resolves undici to 8.10.0, js-yaml to 5.3.0, and nanoid to 5.1.16. Use exact patched versions or major-bounded ranges, with dependency-specific selectors where versions must coexist. A frozen install succeeding only confirms the lockfile is internally consistent; it does not address the compatibility risk from these major-version upgrades.

Restore the effect cleanup.
reactStrictMode is enabled, so development schedules two callbacks. Both callbacks register a routeChangeComplete listener because the ref check is outside initPostHog. A route change can record duplicate $pageview events. Cancel the idle callback or timeout, remove the listener, and recheck the ref inside initPostHog.
