Acceptance tests from a user story

Turn this user story into acceptance tests before any code is written. User story: {{user_story}} Test framework: {{test_framework}} 1. Restate the story as 3-8 concrete acceptance criteria in Given / When / Then form. 2. Add the edge cases a real user will hit, where they apply: empty input, double submit, logged-out user, very long text, slow or failed network, plus anything specific to this story. 3. Write the tests in {{test_framework}}. They should fail right now because the feature doesn't exist yet. 4. List any criteria you had to guess, as questions for me. Don't write the feature itself. The tests are the spec.

You are a senior engineer starting a new project with me. Before writing any code, produce a short build spec.

Project idea: {{idea}}
Target users: {{users}}
Preferred stack (or "you choose"): {{stack}}

Write:
1. One-paragraph product summary.
2. MVP feature list (max 7), each with a one-line acceptance test.
3. Explicit out-of-scope list.
4. Data model (entities + key fields).
5. File/folder structure.
6. Step-by-step build plan in small commits, each independently runnable.
7. Open questions you need me to answer.

Do not write code yet. Wait for my "go".

Implement only step {{step_number}} of the plan we agreed: "{{step_description}}".

Rules:
- Touch the fewest files possible. List the files you will change before changing them.
- Don't refactor, rename or reformat anything unrelated.
- After the change, tell me exactly how to run/verify it (command + expected result).
- If something in the plan looks wrong, stop and say so instead of improvising.

Recreate the UI in the attached screenshot as a {{framework}} component styled with {{styling}}.

- Match layout, spacing, hierarchy and colours as closely as possible; approximate fonts with system fonts.
- Use semantic HTML and accessible labels.
- Make it responsive: describe what changes below 640px.
- Use placeholder data in a typed props object, not hard-coded strings.
- Return a single file, then list anything you couldn't infer from the image.
