E2E Test Selection:
All 12 changed files are pure deletions of two unused UI components: ContractBox and ContractBoxBase from app/component-library/components-temp/Contracts/.

Key findings:

1. All changes are file deletions — no new code was added, only removed.
2. No consumers exist — grep searches for ContractBox, ContractBoxBase, and from.*ContractBox across all .tsx, .ts, and * files returned zero matches. These components were completely unused in the codebase.
3. Dead code cleanup — this is a straightforward removal of orphaned component library files (component, styles, types, constants, tests, and index files for both ContractBox and ContractBoxBase).
4. No impact on any user flows — since nothing imports these components, no E2E test scenarios can be affected by their removal.
5. No performance impact — no rendering, state management, or data loading code was changed.

No E2E tests need to run for this change, and no performance tests are warranted.

Performance Test Selection:
Pure deletion of unused UI components with no consumers. No rendering, state management, or data loading code was changed. No performance impact possible.
