// IMPORTANT: Do NOT expose these as CSS custom properties.
// Use these Sass variables to compile to static CSS values.
// The only CSS custom properties available are those in wp-base-styles:
// - --wp-admin-theme-color
// - --wp-admin-theme-color--rgb
// - --wp-admin-theme-color-darker-10
// - --wp-admin-theme-color-darker-20
// - --wp-admin-border-width-focus
