@Gandalf-the-Blue sorry for the late response,
i changed the background color to mantle and the box color to base because i didn't like the boxes being darker,
and i think surface0 for the boxes, and surface1 for the things on top of the boxes like number of movies looks bad. it also seems to have bad contrast on the numbers with no other style changes.

i changed the accent color highlight because it also affects stuff like number of tv shows, and stats like that but it has a weird dark color on those elements
