caching-diagram.html into the repo root and GitHub Pages will serve it
as a normal webpage that Notion can link to or attempt to embed.
caching-diagram.html with your final animated HTML.basetenlabs/temp-animations.
Homepage: https://basetenlabs.github.io/temp-animations/
Direct artifact: https://basetenlabs.github.io/temp-animations/caching-diagram.html
In Notion, the direct page URL usually behaves better than a GitHub Releases asset URL because it is served as a normal webpage instead of a downloadable release file.
