microsoft/renderformer
A Cornell box turned into a cover page: a red, green and blue cube logo, a two-line ruled title, a black gallery of rendered scenes, then a nested contents list that maps the whole manual.

Checked against the rendered page. Three table-of-contents anchors in the README (#usage-1, #inference-with--renderformerrenderingpipeline-, #bring-your-own-scene-) do not match GitHub's generated heading ids, so those links do not jump; recorded in Section Outline.
Why it is here
A model first screen: a square logo, centered title, author line, venue line, a sharp captioned teaser grid, a single row of text links, then a full nested table of contents that maps the whole manual before installation starts.
