Two layers: an always-on cloud layer holding accounts, ledger and invoices, and a home GPU host running Ollama and Blender that connects outbound through a tunnel with no open ports.
Idle GPU, billed at cost

Two services, one trust boundary

Always on

Accounts · ledger · invoices Reachable with your PC off

Outbound tunnel

No open ports The host connects out; nothing connects in

Your machine

Ollama · Blender Only while powered on

kWh rate × GPU watts = price. No markup.
