Every deploy draws its own plate

A deploy SHA is just a number. Feed one to a seeded pen and it traces a single continuous copper line — a harmonograph that winds down to rest. The mapping is arbitrary but fixed: the same SHA always draws the same plate, so each of these is plotted from a real deploy.

SHA → seed → pen: a fold of the hex into a 32-bit seed drives a mulberry32 PRNG. It's deterministic and reproducible — the plate is generated from the SHA, it doesn't encode what the commit changed.
