…st storms When a page has 50+ image viewers synced by resolution, zooming in one viewer would trigger zoomTo/panTo on all others, causing a massive spike of tile requests and animations. Use IntersectionObserver to track which viewers are near the viewport (200px margin) and only sync those. Off-screen viewers catch up instantly (no animation) when they scroll into view. https://claude.ai/code/session_01HTJYHmtsz7SkLWhWuDLvCR
