This onboarding bottom sheet introduces the photo stacking feature in Google Photos using a looping preview animation. A grid of individual, similar photos smoothly shrinks and collapses into a single stacked card, accompanied by a badge displaying the count of stacked items. Once stacked, the grid scrolls vertically to reveal the next set of photos (e.g., dogs, tropical landscapes), which repeat the stacking sequence. This dynamic illustration clearly communicates the benefit of clutter reduction before the user taps the primary action button.
