Walkthrough

NFT image rendering refactored to use a clipped, rounded container. Image widget moved inside container with zoom-based positioning and center alignment. Title anchor updated to reference the container instead of the image directly.

Changes

Cohort / File(s)	Summary
NFT Image Container & Layout core/src/trezor/lvglui/scrs/nftmanager.py	Introduced nft_image_container to clip corners, apply radius, and disable scrolling/clicking. NFT image now positioned inside container with zoom level 243 and center alignment. Title alignment anchored to container for proper spacing.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~12 minutes

• Verify container properties (clipping, radius, event bubbling) are correctly configured
• Confirm zoom level 243 and center alignment produce intended visual result
• Check title anchor reference and spacing calculation relative to container
