OpenSwiftUI-2048 renders an empty board and an incomplete background #1

OpenSwiftUI-2048 does not render correctly in the iOS Simulator with OpenSwiftUI 0.24.0.

Steps to reproduce

1. Clone OpenSwiftUI-2048 at branch main.
2. Run the 2048 target in an iOS Simulator.
3. Observe the initial screen.

The project uses OpenSwiftUI-spm 0.24.0. The unsupported .drawingGroup(opaque: false, colorMode: .linear) modifier is commented out.

Expected behavior

The board displays a 4×4 grid and initial numbered tiles. The game background fills the screen.

Actual behavior

• The “2048” title and board background are visible.
• Neither the empty grid cells nor numbered tiles are visible.
• The game background stops above the bottom of the screen, leaving a large white area.
