9anime New Design - Classic Width

_{update: looks like this script may not be needed for the time being as 9anime has reverted to the classic site design... we'll see if it lasts

having seen some people on Reddit not being too happy with the new design, I made a change to more closely resemble the classic site design:
- page width is modified to be like before (not full screen width)

btw, if anyone easily wants a layout more like the classic site, you can try temporarily using https://9anime.id/updated}
