lifeaboutgreatgift/mood-tracker ? reverse-engineered prompt

Build me a simple mood tracker web app where I can quickly log how I am feeling each day.

I want a clean, friendly React app that lets me pick a mood, add a short note about why I feel that way, and save it so I can look back later. Please make the main screen easy to use, with a clear way to add a new entry and a list or timeline of past moods. It would be great to see my mood history at a glance, maybe with basic summaries or a simple chart so I can notice patterns over time.

Keep the design calm and modern, and make sure it works well on mobile too. If you need to look up any current docs or best practices, feel free to do that. I mainly want something polished, lightweight, and ready to run as a small personal project.
