vinceau/bibleshow ? reverse-engineered prompt

Build me a simple web app called BibleShow that feels like a PowerPoint for Bible verses. I want to be able to open it in a browser, type in a passage, and have it display the scripture in a big, clean, easy to read format for a room full of people.

Make the experience very straightforward, with a large main display, a way to move through verses or slides, and controls that are easy to use during a presentation. Keep the design minimal, polished, and readable from far away. Use the existing HTML, CSS, fonts, and JavaScript setup, and make sure it works well as a single page style app.

If anything is unclear, use sensible defaults and look up current docs online if you need to. I mostly want a working polished presenter that can show Bible passages clearly and smoothly.
