call for help from anyone who understands how the webpack stuff Masto uses works
@noiob hmm, looking at the (quite sparse) docs, maybe components.scss might do it?
from your top-level, that's app/javascript/styles/mastodon/components.scss
(i pulled that name from https://glitch-soc.github.io/docs/contributing/frontend/#file_folder-the-styles-folder, and looked for the file on your github repo)
