## Summary Replaces the `IntersectionObserver` implementation from #39299 with …the native `loading="lazy"` attribute on the iframe. All supported browsers (Chrome 77+, Safari 16.4+, Firefox 121+) handle this, and the browser-determined threshold adapts to connection speed — generally smarter than a fixed pixel margin. - Drops ~20 lines of JS and the feature-detection fallback - Removes the `lazyLoadMargin` option (no longer configurable — browser decides) - `lazyLoad: false` still opts out by setting `loading="eager"` - Admin embedding snippet updated to drop the `lazyLoadMargin` line Shipped two days ago in #39299, so no external consumers should depend on `lazyLoadMargin` yet. ## Test plan - [ ] Full app embed below the fold — verify iframe defers loading until scrolling near it - [ ] Full app embed above the fold — verify it loads immediately - [ ] `lazyLoad: false` — verify immediate loading, same as pre-#39299 behavior - [ ] Standard (non-full-app) embed — verify unchanged behavior
