Design Issue: Website Width Overflow

I have identified a design issue on the websites homepage where the website's width expands beyond the screen size, negatively impacting the user experience. This issue causes horizontal scrolling for users on smaller screens and can lead to a frustrating browsing experience.

Start at the website homepage and reproduce the horizontal overflow on a smaller screen, then inspect the CSS controlling the page width. The work is done when the homepage fits within the viewport without horizontal scrolling; the issue names no specific file or test to run.
