E2E Test Selection:
The PR introduces 6 new files (4 production, 2 test) that are purely additive:

1. QRSigningContext.tsx - New React context for QR signing state management
2. useQRSigningState.ts - New hook that reads from Redux qrKeyringScanner state and provides QR scan request management
3. contexts/index.ts - Adds exports for the new context
4. hooks/index.ts - Adds export for the new hook
5. Two corresponding test files

Key findings from investigation:

• No existing production files import useQRSigning, QRSigningContext, or useQRSigningState - these are not yet consumed anywhere
• The HardwareWalletProvider.tsx (which wraps the entire app via Root/index.tsx) has NOT been modified
• These changes are purely preparatory/foundational for future QR hardware wallet signing functionality
• No existing E2E test flows are broken or affected by these additive changes

Why SmokeAccounts: The SmokeAccounts tag explicitly covers "adding QR-based hardware wallet accounts" - this is the feature area these new files are building toward. Running SmokeAccounts validates that the existing QR hardware wallet account flow still works correctly and that these new additions don't inadvertently break anything in the hardware wallet infrastructure.

No performance impact: These are new, unused context/hook files with no rendering or data loading changes to existing components.

Performance Test Selection:
The changes are purely additive new files (context and hook) that are not yet consumed by any production component. There are no changes to rendering, data loading, state management of existing components, or any critical user flows. No performance impact expected.
