How to do list fragments?

```
@ul
- what happens when you add a new Todo item?
- how does it get to the server?
- where does the server save it?
- what happens on start up?
@ulend
```

The issue does not name a file, test, or entry point. Start by locating the Markdown deck and its Reveal.js configuration, then determine how list fragments should be represented and verify that the Todo flow is documented or demonstrated from item creation through server storage and startup.
