Prototype. This Blueprint is catalog metadata only. The build content below is a structural preview — the real, verified instructions have not been written yet.

Overview

What you are building and why the design choices matter. This section will set out the goal, the approach, and what you should understand before starting — not just a parts list.

Requirements

Parts, tools, software, and prerequisite knowledge will be listed here, with notes on substitutions and the compatibility constraints that actually matter.

Build

Step-by-step assembly and configuration, with an explanation of why each step works so the process is repeatable rather than copied blindly.

Testing / Verification

Concrete checks to confirm the build behaves as intended, and how to tell the difference between “working” and “works for now”.

Troubleshooting

Predictable failure modes and how to diagnose them — what to check first, and what a healthy system looks like at each stage.

Upgrades / Modifications

Optional extensions and variations, collected here once the core build is solid so they do not distract from a first attempt.
