* - classnames => (array) an array of classnames to be returned for block styles. The key is a classname or pattern.
|
|
* A value of `true` means the classname should be applied always. Otherwise, a valid CSS property (string)

|
* The key should be the CSS property name that matches the second element of the preset string value,
|
|
* i.e., "color" in var:preset|color|somePresetSlug. The value is a CSS var pattern (e.g. `--wp--preset--color--$slug`),

|
|
* - property_keys => (array) array of keys whose values represent a valid CSS property, e.g., "margin" or "border".
|
|
* - path => (array) a path that accesses the corresponding style value in the block style object.
|
|
* - value_func => (string) the name of a function to generate a CSS definition array for a particular style object. The output of this function should be `array( "$property" => "$value", ... )`.
