Hello333k/Emi-Calculator ? reverse-engineered prompt

Build me a fast, responsive financial calculator website that works fully in the browser with no tracking or accounts. I want two main tools in it, one for loan EMI and one for savings planning.

For the EMI side, users should be able to enter loan amount, interest rate, time period, and a down payment, then see the monthly payment, how much interest they’ll pay, a clear breakdown of principal and interest, and a full repayment schedule they can export to CSV. It should also let people test extra payments and see how that changes the loan.

For savings, I want both a growth calculator and a goal calculator. People should be able to add recurring deposits, one time deposits, choose how often interest compounds, and see how their money grows over time with charts and milestones. It should also support things like step up contributions, fees, inflation, and different rate scenarios.

Make it look clean, work well on mobile, support dark mode, and let users share their results with a link.
