Hippo-critical

GitHub renders Markdown in a pull request, but you can't comment on that rendered view, only the raw diff. CSV doesn't render at all. git-format fixes both: it renders the file next to the diff, and every line is clickable straight into GitHub's own comment form. No token, no server, nothing sent anywhere. Works on .md, .markdown, .mdx, .csv and .tsv files. Shows line numbers on every block and table row, marks what changed, badges existing comments, and lets you switch between the whole file and just the changes. Large files load on demand, since GitHub hides big diffs behind its own button. Mermaid diagrams get a render button too, loaded only when you use it. Two known gaps: collapsed <details> blocks render open (the content is what you're there to read), and the classic "Files changed" view isn't supported — it says so rather than pretending to work. No permissions requested, no network requests made. Only runs on github.com pull request pages.
