Fine, I made my own Markdown to HTML document generator (with Blackjack and hookers):

https://github.com/v-p-b/sugardocy

It takes a single MD file, and outputs a single, self-contained HTML file without downloading the kitchen sink.

Contributions are welcome, esp. if you have better taste and frontend skills than I do.
