ksky521/nodeppt ? reverse-engineered prompt

Build me a slick web based presentation tool that lets me write slides in a single markdown file and then preview, present, and export them easily.

I want to be able to create a new deck from a template, run a local server to present it, and build a final version for sharing. It should support speaker notes and a presenter view that syncs across screens, plus normal keyboard controls for moving through slides, fullscreen, overview, and notes.

The slide syntax should support custom backgrounds with images or video, simple layout and styling helpers, nice animations, and a few built in extras like charts, flow diagrams, and math formulas. If there’s a public folder with assets, let me use it directly in the deck and have it copied into the build output. Make it feel polished in the browser, especially in Chrome, and look modern right out of the box.
