inforkgodara/store-pos ? reverse-engineered prompt

Build me a desktop point of sale app for a retail or wholesale store in Java with a simple JavaFX interface.

I want the core screens and workflows for purchase, sales, inventory, receipts, payments, and basic journal entries, with a clean dashboard that makes it easy to use at the counter. It should connect to a database, support product and stock management, and be able to print receipts and reports nicely. If it helps, include sensible sample data or a small demo database so the app can run right away.

Please keep it practical and close to a real store workflow, with forms, tables, search, and common actions like add, edit, save, delete, and print. If you need to check current docs for any library or JavaFX detail, go ahead and look them up online. Also make the code organized so it would be easy to extend later with more finance and ERP features.
