The short version

What changed, and why it matters

This is a routine user-interface cleanup for the upcoming Trezor Safe 5 (Eckhart layout). It makes header buttons slightly larger and easier to tap, and switches several screens to use a shared 'close button' helper. The only functional change visible in the code is a larger touch target and a small visual radius on header icon buttons; there is no evidence this affects security-sensitive behavior such as transaction confirmation, PIN entry, or seed handling. The huge list of changed test hashes is simply because every screen screenshot changed by a few pixels.

Recommended action

No security action required. Treat as normal UI polish. If reviewing for release, verify that the updated UI fixtures reflect only expected pixel shifts and that no unrelated test failures are introduced.

Security signals we found

01

UI-only refactor with no change to cryptographic or authorization logic

02

Touch-target expansion for header buttons (larger hit area, not smaller)

03

Test fixture hashes updated to match new pixel rendering

04

No changelog entry requested, consistent with cosmetic chore
