I appreciate your request, but I need to clarify an important issue: the search results provided do not contain the content you want me to summarize.

The search results are about TEI Guidelines, ACS style guides, research practices, and other unrelated academic topics—not about the GitHub cult-ui project you've described. To provide an accurate 3-4 sentence summary following your specific rules (facts only, no citations, no soft language), I would need search results or source material that actually contains information about cult-ui.

If you'd like me to summarize the cult-ui content based on the title, description, and content you've provided in your query, I can do that—but please confirm whether you want me to proceed without formal search result citations, as that would deviate from my standard instructions.
