Mini App Brief

ROLE:
You are a senior frontend developer helping a beginner plan a Vibe 102 mini app.

CONTEXT:
I already have a clean React + Vite + Tailwind starter project running on localhost.
I need a project brief before I ask my coding agent to build the app.

APP CHOICE:
[mission task tracker / habit tracker / expense tracker / project bookmark manager / lead tracker / study flashcards / mini journal / recipe idea saver]

RULES FOR THE APP:
- one list of items only
- add item
- update or mark item
- delete item
- save with localStorage
- no backend
- no login
- no database
- no charts
- no API
- no image upload
- no multi-page routing

TASK:
Ask me these questions before finalizing:
1. What is the app called?
2. Who is the app for?
3. What should one item contain? Keep it to 3 or 4 fields.
4. What update action should the item have?
5. What theme do I want? Suggest 8 beginner-safe themes.
6. What colors, mood, or style should the app avoid?
7. What would make this app too big for tonight?

After I answer, create the final brief.

FINAL BRIEF FORMAT:
- app name
- user goal
- selected app type
- one item data shape
- max 3 core features
- design/theme direction
- layout sections
- localStorage key name
- build order
- test checklist
- out-of-scope list

Then create a second copy-paste block titled IDE PROMPT: Save project-brief.md.
That IDE prompt must include the full final brief and tell the coding agent to create a file named project-brief.md in the project root.

Rules:
- keep it simple enough to build in 2.5 hours
- keep it as one list of items
- do not add login, database, payment, AI feature, dashboard, chart, API, image upload, or multi-page routing
- make the design direction practical for Tailwind
- end with the next build checkpoint: Data Shape
- make the IDE prompt complete so I can copy and paste it without rewriting anything

CONTEXT:
I finished my Vibe 102 project brief.

TASK:
Create a new file named project-brief.md in the project root.

CONTENT:
[the full final brief should already be included here by ChatGPT]

Rules:
- preserve the brief scope
- do not build app features yet
- do not rewrite the app idea
- after creating the file, tell me the file path and stop
