Thanks for getting this in! Overall, everything looks good. Some minor nitpicks are some python linters errors and some formatting inconsistent with the other project code (some functions without two spaces between them, x=y instead of x = y for keyword variable assignment in functions). It looks like the linter does not track this, although keeping the formatting consistent helps with searching the project. You don't need to worry about these as you are coding; just make sure to run the formatter on each file you include in a PR (shift + alt + f or shift + command + f). I made the changes, although I am mentioning them for future PRs.

Another thing I suggest as a todo is to make it easier to see the Contribution amount by increasing the area around the lines that make it appear. It seems like I need to have the tip of my mouse pointer exactly on the line for the pop-up to appear.

Also, make sure to use npm ci instead of npm install when installing new dependencies after pulling.
