HiEventsDev/hi.events ? reverse-engineered prompt

Build me a self hosted event ticketing and management app for organizers. I want to be able to create events, sell free or paid tickets, handle promo codes, add ons, taxes and fees, and support things like conferences, concerts, workshops, and festivals.

It should have a clean organizer dashboard, branded event pages, customizable checkout, PDF tickets, and a ticket widget I can embed on another site. I also need attendee tools like custom questions, search and filtering, CSV export, refunds, bulk messaging, and QR code check in with logs.

Please make it feel modern and polished, with multi user access, reports for sales and revenue, and a simple API for integrations. If anything is unclear, look up current docs online and match the existing project style. I’d like it to run locally with Docker and be ready for self hosting.
