You never have to design from a blank canvas unless you want to. Every fresh environment offers a way in that matches how much control you want.
Every empty environment opens with Blueprint. Pick how much control you want, answer a few questions, and Linexa lays out the components, wires them together, and quotes the monthly cost before anything is deployed.
Every environment is its own isolated Google Cloud project with its own service-account key. Nothing is shared by default, and nothing silently falls back to another environment's credentials.
Every mode ends up in the same place: a real, editable canvas ready to deploy.
