How it is used

Trace's agent reads this design as context — what parts a board like this carries, how they are grouped across sheets, what a plausible layer stack and board size look like for the job. It is not copied. The licence above is permissive, and it, the repository and the commit are recorded so the origin of anything derived from it is always answerable.
