Show HN: DECK0 – a ~17 KB CLI that serves a Markdown file as a slide deck (opens in new tab)

Tired of PowerPoint overhead and reveal.js scaffolding for quick technical talks. DECK0 takes a plain .md file and serves it as a slide deck via a local Node HTTP server.

`npx @tforster/deck0 your-talk.md`

Slides split on ## headings. Syntax highlighting, Mermaid diagrams, GFM tables, and callouts. Also accepts a remote URL instead of a local file. No build step, no config, no framework.

You can demo it with `npx @tforster/deck0 https://raw.githubusercontent.com/tforster/deck0/main/demo/p...`
