# Design contract `design-system/sql-server-qai/MASTER.md` is the contract the UI is built against: dark workbench palette, type scale, spacing, component rules, and the reason the accent is reserved for action and state rather than decoration. The Hallmark audit log in `.hallmark/log.json` records the decisions taken against it. Two of them shaped the code: no utility CSS framework, and no network font loader.
