In functions.php I want to enqueue scripts based on what page I’m viewing: home page, single page, etc.
It all seems to work except when I go on a blog category.

I tried the following (in functions.php):

is_front_page() -> works
is_page() -> works
is_single() -> works
is_category() -> NOPE.

    function load_ngof_files() {

        wp_enqueue_style( 'ngof_common', get_template_directory_uri() . '/assets/css/com.css');
    
    if (is_front_page()) {
        // echo "front page";   
    wp_enqueue_style( 'ngof_front', get_template_directory_uri() . '/assets/css/front.css');

    } elseif (is_category()) {
        echo "category";
        wp_enqueue_style( 'ngof_cat', get_template_directory_uri() . '/assets/css/cat.css');

    } elseif (is_page()) {
        echo "page";

    } elseif (is_single()) {
        // Blog posts index page
        echo "single";
    }
    
}

add_action('init', 'load_ngof_files' );

Any ideas why? category.php is called correctly.
