mf-dashboard/mf-dashboard.github.io ? reverse-engineered prompt

Build me a local first mutual fund dashboard for Indian investors that runs entirely in the browser. I want to upload my CAMS or KFintech CAS statement, then see my portfolio value, gains and losses, returns, asset allocation, and fund wise performance in a clean modern interface with charts. It should track purchases, redemptions, and switches, calculate XIRR, FIFO based capital gains, and split short term and long term gains by financial year.

Please also add transaction history, portfolio history charts, benchmark comparison against Nifty 50 and Nifty 500, overlap analysis, expense ratio insights, and a simple health score for the portfolio. I’d like support for multiple family members, separate local data for each one, and a combined family view when there is more than one profile.

Keep all data stored locally in the browser, make it feel polished and mobile friendly, and include export options for reports and backup. If you need to look up current docs online for any browser features or charting details, go ahead.
