 Themes that use the same preset slugs as WordPress uses need to be

 From the devnote https://make.wordpress.org/core/2022/01/08/updates-for-

 The CSS for some of the presets defined by WordPress (font sizes, colors,
 and gradients) was loaded twice for most themes in WordPress 5.8: in the
 block-library stylesheet plus in the global stylesheet. Additionally,
 there were slight differences in the CSS in both places.

 In WordPress 5.9 those were consolidated into a single place, the global
 stylesheet whose name is `global-styles-inline-css` that is now loaded for
 all themes in the front-end.

 Each preset value generates a single CSS Custom Property and a class, as

 /* CSS Custom Properties for the preset values */
 body {
   --wp--preset--color--pale-pink: #f78da7;
   --wp--preset--font-size--large: 36px;
   /* etc. */

 /* CSS classes for the preset values */
 .has-<PRESET_SLUG>-<PRESET_TYPE> { ... }
 .has-pale-pink-color { color: var(--wp--preset--color--pale-pink)
 !important; }
 .has-large-font-size { font-size: var(--wp--preset--font-size--large)
 !important; }


 For themes to override the default values they can use the theme.json and
 provide the same slug. Themes that do not use a theme.json can still
 override the default values by enqueuing some CSS that sets the
 corresponding CSS Custom Property.

 Example (sets a new value for the default large font size):

 :root {
  --wp--preset--font-size--large: <NEW_VALUE>;
