My ISP blocked the raw.githubusercontent.com domain (π), so I wrote code to bypass the restriction!
https://githubusercontent.zohan.tech?user={USERNAME}&repo={REPO}&branch={BRANCH}&path={PATH} renders the raw githubusercontent for repo {REPO} by user {USERNAME} at the branch {BRANCH} and file path {PATH}. For example, https://githubusercontent.zohan.tech/?user=Zo-Bro-23&repo=Zo-Bro-23&branch=output&path=github-contribution-grid-snake.svg renders the snake svg that I have in the root folder of the output branch of the repo @Zo-Bro-23/Zo-Bro-23.
