Visual regression: Storybook UI snapshots updated

Mode: UPDATE (triggered by human commit f5de8d9)

Changes: 2 snapshots (2 modified, 0 added, 0 deleted)

What this means:

• Snapshots have been automatically updated to match current rendering
• Next CI run will switch to CHECK mode to verify stability
• If snapshots change again, CHECK mode will fail (indicates flapping)

Next steps:

• Review the changes to ensure they're intentional
• Approve if changes match your expectations
• If unexpected, investigate component rendering
