If you are pointing an AI coding tool here
Fetch /llms.txt for the machine-readable index, or send it to the setup guide, which tells it what to fetch, where to write it, and gives it a CLAUDE.md template.
The rules are in BASELINE.md and every value is in aleris-tokens.css. Those two plus the font stylesheet are the whole load-bearing set.
