Summary:
ScreenshotsHeroBladeRow is inconsistency-sized relative to the rest of the UI.

Affects currently Live Content:
Yes (Marketplace UI in general)

Impact:

• The carousel causes a cumulative layout shift when the ScreenshotsHeroBladeRow becomes visible.
• The "row" version of the screenshot row further down the root store layout is too wide, which means the right-side of the focus ring is obscured.

Repro Steps:

1. Open the Marketplace.
2. Try to navigate to a carousel row that uses the new screenshot layout. Observe that the rest of the content under the carousel is pushed down (aka "cumulitive layout shift").
3. Scroll down to a screenshot row further down in the root layout. Try different client sizes; you'll notice the focus ring isn't fully bordering the row.

Observed Results:
Cumulative layout shift + focus ring out of bounds. The screenshot row further down the root is way wider than other items.

Expected Results:
Cumulative layout should not happen, focus ring should always be visible.
