Scratchpad (internal test-bed) — agent-first

Bootstrap an operator-only scratchpad: one internal page inside the real app where the user looks at and fiddles with their own work-in-progress — judging it by taste and eye, not by assertion. You read the repo, detect its conventions, and write the gate, route, and first sections tailored to that stack. The whole point is that it reuses the real code, never a fork of it, so what the user eyeballs is exactly what ships.

What a scratchpad actually is

A single internal page inside the real app for judging your own work-in-progress — not a public feature, not a test suite, not a separate tool like Storybook. It's the in-app equivalent of a workbench: you keep it because the things you want to judge only render correctly inside the real app (real auth, real theme tokens, real data, real link-building, real rendering pipeline), and you want to judge them by taste and by eye.

It answers questions a test can't:
