Build me a desktop app for a small shop or restaurant that works fully offline and feels fast at the counter. I want a POS screen for quick billing, cart edits, split payments, hold bills, receipt and kitchen printing, plus simple customer friendly token numbering. It should also have admin areas for inventory, product and category management, staff and payroll, daily expenses, reminders, and a dashboard with sales, profit, and basic analytics that can be exported to Excel or CSV. Make it easy to lock sensitive screens with a PIN, support thermal printers, and save everything locally so it keeps working without internet. If it makes sense, include a clean modern UI and a way to manage shop settings like tax, address, and printer setup. Look up current docs online if you need to.
