Crema Line

The morning bar of a small specialty roastery, simulated honestly. Roast a kilo on the drum and watch the rate of rise; grind it and watch the fines tail; tamp it, lock it, and pull it under nine bars while Darcy's law and a compressible coffee cake decide what comes out. Fold microfoam without cooking the protein. The customer's verdict is the number the refractometer gives you, filed into a week-long service ledger — never a star rating. Ships with its own documented, metric, reusable Three.js model library.
