aryan-2206/Banquet_Management_System ? reverse-engineered prompt

Build me a banquet management web app called Banquet IntelliManager for a banquet hall team. I want one place where sales, finance, kitchen, guest check in, DJs, clients, and admins can all work from their own dashboard after logging in with the right role.

The app should let sales create bookings, check date conflicts, and generate quotes. Finance should split payments into installments and make PDF invoices. The client portal should let a host send guest invites, generate QR entry passes, upload party photos, track payment progress, and share song requests with the DJ. Guest relations should be able to scan QR codes from a phone or tablet and mark guests as arrived. The kitchen should see live headcount updates so it can prepare the right amount of food. Admins should manage users and view event summaries.

Use a clean modern UI, real time updates where needed, and make the whole thing feel polished and ready to demo. If you need current docs for any libraries, look them up online.
