Settings are launch policy, made human. Every control here maps to a field the system enforces — but you choose in plain language ("Forgets everything on close"), not JSON. A control can never express an unsafe policy; the mapping is validated. This is how a normal person tunes a compartment without learning the machinery — and the same panel a designer uses to shape a new monomer. "Network" is the real firewall (which apps go online, via which transport), and the device toggles each grant a scoped, revocable bond. Concept render in the PolymerOS design language.
