Live community pins — P2P network

Pins shared via Gun.js peer-to-peer — no central server, no account required. Sensitive category pins are never shared without explicit confirmation.

“You are not a user of this tool. You are its performer, its operator, its witness. When you measure sound, you name a condition. When you pin a location, you make an argument about space, power, and the right to a liveable acoustic environment.”
