The short version

What changed, and why it matters

This commit changes how users confirm an Ethereum authorization screen on Trezor's 'Caesar' layout. Previously, the user had to hold down a button to approve; now a simple tap is enough. The change only affects the user-interface interaction for one specific screen (EIP-7702 authorizations) and updates the corresponding visual test snapshots. There is no direct evidence in the commit that this fixes a security vulnerability, but it could slightly reduce the chance of an accidental or coerced approval if the hold-to-confirm behavior was considered too easy to bypass or too confusing.

Recommended action

Treat as a minor UI-hardening change rather than a critical security fix. Review whether tap-to-confirm provides adequate protection against accidental or malicious EIP-7702 authorizations compared with hold-to-confirm, and ensure the product security team documents the rationale. No urgent patching is indicated by the diff alone.
