Zey4n/lumina-personal-finance ? reverse-engineered prompt

Build me a sleek desktop personal finance app called Lumina for Windows that works fully offline and keeps everything private on the user’s machine.

It should let someone set up a nickname, track cash and GCash balances in Philippine Peso, add income and expenses, and see totals by all time, year, month, week, or a specific date. I also want a simple way to manage debt installments, including automatic deductions when payments are due. The app should understand some local slang or casual transaction names and sort them into useful categories like food or other spending.

Make the interface modern and polished, with a dark mode and a glassy look. Include charts for spending insights, plus export options for PDF and CSV so users can keep records for accounting or taxes. If you need current docs for the desktop build or export libraries, look them up online and keep the whole thing clean, fast, and easy to use.
