Note

Low Risk
Mostly mechanical import/mocking changes to swap Rewards screens and tests over to the new components-temp Skeleton; functional risk is limited to loading placeholders rendering/autoPlay behavior.

Overview
Migrates the Rewards UI (onboarding, season status, previous season, referral details, settings, and tabs) to use the new design-system-backed Skeleton from component-library/components-temp/Skeleton instead of the legacy component.

Updates associated unit tests to mock the new Skeleton module paths and types so loading-state coverage continues to pass.

E2E Test Selection:
All changed files are confined to the Rewards UI feature under app/components/UI/Rewards/ along with their corresponding unit tests. There are no changes to core wallet functionality (Engine, Controllers, navigation, confirmations, network management, trade flows, identity, snaps, etc.) and no modifications to shared components like Browser, TabBar, Modals, or Confirmations. The Rewards feature is not covered by any of the available Detox E2E smoke tags listed, and none of the tag descriptions reference Rewards-related flows. Therefore, running existing E2E smoke suites would not provide additional validation value for these isolated UI changes. The risk of regression to critical wallet flows is low.

Performance Test Selection:
Changes are limited to Rewards UI components and related presentation logic. There are no modifications to performance-critical flows such as onboarding, login, app launch, swaps, asset loading, predictions, or perps. No controller, data layer, or large list rendering infrastructure changes were introduced. Therefore, performance tests are not required.
