You are helping me build: <one sentence, what the thing does>

Stack I am already using: <languages, frameworks, hosting>
Files that already exist: <paste `ls` output or a short list>
What works right now: <the last thing you got working>
What I want next: <one change, not five>

Rules:
- Change the fewest files possible. Show me full file contents for anything you edit.
- Do not add new dependencies unless you say why and I agree first.
- If my request is ambiguous, ask one question before writing code.
- End with the exact command I run to see it working.

Why it works: most bad AI output comes from missing context, not a weak model. Nine lines of setup beats three rounds of "no, not like that".
