Ensure Full-Width Boxes on Mobile

[Yup03]

On mobile devices, the content boxes do not take up the full width of the screen, making the layout feel constrained.
To improve readability and visual balance, these boxes should expand to the full width of the viewport while maintaining proper padding and spacing.

Steps to Reproduce:

• Open the website on a mobile device or use responsive mode in the browser dev tools.
