What doesn't exist
To save you time searching: Ultimate Cursor has no shortcodes, no Gutenberg blocks, and no public JavaScript events (no CustomEvent/dispatchEvent API on the frontend runtime). Cursors and backgrounds are configured entirely through the dashboard and apply automatically by scope rule — there's no per-post or per-template placement mechanism to hook into.
The @wordpress/hooks JS filters used internally (is-pro-feature, cursor-types) are admin-dashboard implementation details for the Pro unlock UI, not a public developer API — they're not documented here as something to build against.
