marhi/diblong ? reverse-engineered prompt

Build me a premium multilingual ecommerce shop for the Diblong brand, with a polished storefront for shoppers and a simple admin area for managing the store. It should support Slovenian as the main language, plus English and Croatian, and the site should use clean localized URLs, good SEO, and look solid on mobile and desktop.

I want product pages, category browsing, a cart and checkout flow, shipping options, promos, and a few CMS style pages like about and delivery info. The admin side should let staff manage products, orders, content, and basic settings, and there should be login with different roles for customer, staff, and admin. Use a real database, make it ready for local development with Postgres, and include seeded sample data so I can see the full store right away. If you need to, look up current docs online for the best way to wire up the modern Angular and API setup.
