Removing Featherlight from Posts Page

I found Featherlight including JS and CSS on the posts page and no way to remove it. I couldn’t find a ready answer on Google, so I’m posting this for future searchers.

The “disable” option isn’t available when a page is set as the posts page. Even if “Disable lighbox” is selected before making a page the posts page, Featherlight code is included (WP ver 5.7.1, Featherlight ver 1.3.4).

Here’s my snippet for the functions file to disable lightbox on the posts page.

function disable_featherlight_posts_page() {
		if ( is_home() ) {
			add_filter( 'wp_featherlight_load_css', '__return_false' );
			add_filter( 'wp_featherlight_load_js',  '__return_false' );
		}
	}
add_action( 'init', 'disable_featherlight_posts_page' );

If there’s a better way, please post it. Is “init” the right hook for this action?

And thanks for the simple, nicely lightweight plugin.
