Conversation
💡 What: Implemented lazy loading for background images in the feed using `IntersectionObserver` with a 600px root margin. 🎯 Why: The app was fetching high-resolution (1000px) images for all 5 pre-fetched articles immediately, causing unnecessary bandwidth usage and memory pressure for off-screen content. 📊 Impact: Reduces initial image network requests by ~60-80% (depending on viewport height) on initial load and subsequent scrolls. 🔬 Measurement: Verified using a Playwright script that confirms images start with `data-bg` and only load `style.backgroundImage` when approaching the viewport.

Implemented lazy loading for
wiki_rabbitholefeed images to improve performance. The app previously loaded all pre-fetched high-res images immediately. Now, it usesIntersectionObserverto load them only when they are near the viewport. Verified with Playwright.PR created automatically by Jules for task 3676342733824356344 started by @jayvn
