* Presets are a set of values that serve

* 'slug' => 'unique-name-within-the-set',
* 'name' => 'Name for the UI',
* <value_key> => 'value'
* ),
* )
* ```
*
* This contains the necessary metadata to process them:
*
* - path => where to find the preset within the settings section
* - value_key => the key that represents the value
* - value_func => the callback to render the value (either value_key or value_func should be present)
* - css_vars => template string to use in generating the CSS Custom Property.
* Example output: "--wp--preset--duotone--blue: <value>" will generate as many CSS Custom Properties as presets defined
* substituting the $slug for the slug's value for each preset value.
* - classes => array containing a structure with the classes to generate for the presets.
* Each key is a template string to resolve similarly to the css_vars and each value is the CSS property to use for that class.
* Example output: ".has-blue-color { color: <value> }"
* - properties => a list of CSS properties to be used by kses to check the preset value is safe.
