dARSHANdR4/automated-nse-eod-report ? reverse-engineered prompt

Build me a simple web app that generates an end of day stock market report for a few NSE indexes like NIFTY 50 and the midcap and smallcap groups.

I want a dropdown to pick an index, a button to refresh the report, and then a clean dashboard that shows the market snapshot, how many stocks are up or down, a few biggest gainers and losers, volume and daily range highlights, and a watch section for stocks near their 52 week highs or lows when that data is available.

It should also let me download the report as a PNG image and as a CSV file. Make it feel easy to use in the browser, with a polished layout that I can open on a hosted site without setting anything up locally. If you need to look up current docs or examples for the data or charting pieces, go ahead and do that.
