IbrahimFaisal12/salespd ? reverse-engineered prompt

Build me a simple web app for exploring the Superstore sales dataset.

I want a clean dashboard where I can load the CSV, see the main sales numbers at a glance, and browse the data in a table. It should feel polished and easy to use, with a good looking home screen, clear charts, and basic filters so I can slice the data by things like category, region, and date. If it makes sense, add a way to import or connect the data through Supabase so the app can store and read the sales records properly.

Please make it work well as a modern React app and keep the UI responsive for desktop and mobile. Use the dataset already in the project, and if you need to look up current docs online, go ahead. Focus on making the experience smooth, useful, and visually appealing, like a small sales analytics dashboard I could actually use.
