Where are presets stored?

A template's preset files are essentially the same as the templates theme files just stored in the following folder:

yoursite.com/templates/[your zgf4 template]/settings/themes/presets

Presets use the following naming convention to highlight the fact that they are examples.

theme.[example]-blank.json

Preset files are automatically merged into the theme dropdown list.

The contents of a preset file are the same as the content in theme files.
