[WIP] Fix layout issue with game board visibility under header

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

The current game design has a layout issue where the top of the board is partially hidden under the header containing scores and player information. This results in the top bricks not being easily selectable, which impacts gameplay.

Steps to address:

1. Adjust the layout to ensure that the board starts below the header.
2. Add proper margins or padding as needed to create a clear separation between the header and the game board.
3. Verify that the game board's visibility and interactivity improve across various screen sizes, especially on mobile devices.
