The Global Styles interface in the Site Editor updates a custom post type (CPT) called wp_global_styles.
Using my oik-types plugin I changed the registration so that this CPT was, in addition to the original settings : Publicly queryable, Show UI, Show in menu and Show in admin bar. This gave me access to the Global Styles from the admin menu.
I then copied the contents. It’s fairly unreadable in its minimised mode.
{"isGlobalStylesUserThemeJSON":true,"styles":{"core/navigation":{"typography":{"fontSize":"13px","fontStyle":"normal","fontWeight":"700"},"color":{"text":"#eeeeee"}},"core/site-title":{"typography":{"fontSize":"36px"},"color":{"text":"#eeeeee","link":"#eeeeee"}},"core/site-tagline":{"color":{"text":"#ffffff"},"typography":{"fontSize":"36px"}},"root":{"typography":{"fontStyle":"normal","fontWeight":"500","fontFamily":"Open Sans, sans-serif"},"color":{"text":"#616161","link":"#3498db"}},"core/heading/h1":{"color":{"text":"#eeeeee"}},"core/heading/h2":{"color":{"text":"#616161"}},"core/template-part":{"color":{"link":"#3498db"}},"core/cover":{"spacing":{"padding":{"top":"100px","right":"100px","bottom":"100px","left":"100px"}}}}}It looks better when pretty printed using a JSON formatter.

Theoretically, I should be able to merge the contents from the database with the theme.json file. Then, when used in other sites, resetting global styles would revert to customised version.
