Error Message:

Recommended Action
- Download the new
ShellBadge*.png snapshot files from the build 1456236 artifacts and inspect the visual difference.
- If this is an intentional visual change (e.g., a fix landed for Shell tab badge rendering on iOS), update the baseline images in the test assets.
- If this is a regression, investigate recent commits touching Shell tab badge rendering on iOS — search
src/Controls/src/Core/Shell/ and platform-specific iOS Shell handler code.
- The consistent failure across all 4 iOS variants (not Android API 30 which passes) indicates an iOS-specific rendering change.
