/**
* Runs the theme.json webfonts handler.
*
* Using `WP_Theme_JSON_Resolver`, it gets the fonts defined
* in the `theme.json` for the current selection and style
* variations, validates the font-face properties, generates
* the '@font-face' style declarations, and then enqueues the
* styles for both the editor and front-end.
*
* Design Notes:
* This is not a public API, but rather an internal handler.
* A future public Webfonts API will replace this stopgap code.
*
* This code design is intentional.
* a. It hides the inner-workings.
* b. It does not expose API ins or outs for consumption.
* c. It only works with a theme's `theme.json`.
*
* Why?
* a. To avoid backwards-compatibility issues when
* the Webfonts API is introduced in Core.
* b. To make `fontFace` declarations in `theme.json` work.
*
