Looking at your screenshot, I can see the website is experiencing layout shift and jank, particularly with:

1. The features section (All-Day Battery card) appearing to shift
2. Possible horizontal scrollbar appearing/disappearing
3. The proof notification popup continuously appearing every 3-10 seconds, causing constant page reflow

The main culprit is the proof notification constantly triggering every few seconds. Let me disable or significantly reduce its frequency to stabilize the page:

Now I'll increase the delay between notifications to reduce the constant page reflow:

Now let me check the features section for any overflow issues:

The features section looks fine. Let me check the page layout to ensure there's no horizontal overflow:

Let me add a safety measure to prevent any horizontal overflow in the main layout:

Fixed the website shaking by making three key changes: 1) Increased the proof notification interval from every 3-10 seconds to every 15-25 seconds, dramatically reducing how often the page reflows; 2) Added overflow-x-hidden to the main element to prevent any horizontal scrollbar jank; 3) Ensured fixed positioning on the notification doesn't cause layout shifts. The page should now feel much more stable and smooth when browsing.

Updated the proof notification timing back to 5-10 seconds. Notifications now appear every 5-10 seconds instead of 15-25 seconds, showing more frequent social proof while maintaining reasonable performance.
