backupghofar-commits/tamima-booking-dashboard ? reverse-engineered prompt

Build me a hotel booking profitability dashboard for TAMIMA that feels like a small business app people can actually use every day.

I want it to let staff enter booking details, customer and hotel info, payment terms, and rates in SAR and IDR, then automatically calculate total bills, remaining balance, profit, and margin. It should clearly show whether a booking is paid, unpaid, or still a draft, and keep saved records in the browser so we can search, filter, sort, and manage older bookings later.

Please also include a clean confirmation letter view that can be printed, saved as PDF, exported to Word and Excel, or shared quickly through WhatsApp and email. Make it responsive for desktop and mobile, support offline use like a PWA, and feel polished enough to install on Windows or a phone. Keep the interface simple, professional, and easy for non technical staff to use.
