keyword is the key part...

If the preceding line is a list entry (i.e. starts with '-'), then
it's 4 more spaces. It's always 2 more spaces than the preceding
keyword start (aka json-schema vocabulary).
Arguably, this style is a bit inconsistent in that the '-' counts
toward as indentation of the current line, but not the preceding line.
However, I think this style is a bit less error prone and easier to
review. With the other style (always N more spaces) it's harder to
distinguish lists vs. dicts. For example, you can have something like
this:
- key:
- foo
- bar
- key:
foo
bar
- key:
- foo
bar
All 3 of these could be valid. Which one was intended? (Can't really
tell here, but you can with actual DT schema.)
