Culture of practice
The Playground
How UTP practises craft in public — build, break, and fix together. This page explains the culture. Your Sandbox is the signed-in workspace where the work lives.
Playground = this culture explainer. Your Sandbox = your builder home after you create an account. The Sandbox for the New Salt = our mythology — not a separate product page.
