- scan-qr screen: dark background, native shadow instead of unsupported boxShadow, safe-area aware scroll padding
- my-qr-code-card: dark surface/text colors, ellipsize long username/address instead of overflowing
- qr-toggle-tab: dark tab colors, drop unsupported css box-shadow class in favor of a platform shadow style
- scan-camera-view: dark placeholder/button colors
- shared header: derive icon/text color from color scheme when no explicit textColor is passed
