For example, I have two headers
header.twig
и
new-header.twig

I need to validate the header on the page and plug in scripts and styles depending on the header.

Translated with DeepL.com (free version)

I’ve done it like this

// Get the context of the current page
$context = Timber::get_context();

if (isset($context['header_type']) && $context['header_type'] === 'new') {
    // This is the new header
    // Connect the appropriate styles
    wp_enqueue_style('new-header');
    wp_enqueue_style('new_post_style');

} else {
    // This is the standard header
    // Connect standard styles
    wp_enqueue_style('google-fonts');
    wp_enqueue_style('select2');
    wp_enqueue_style('animation-css');
    wp_enqueue_style('fancybox-css');
    wp_enqueue_style('swiper');

    wp_enqueue_style('new-style');
    wp_enqueue_style('new-water-heater');
    wp_enqueue_style('heat-pump');

    // Connect the corresponding scripts
    wp_enqueue_script('foundation');
    wp_enqueue_script('what-input');
    wp_enqueue_script('fancybox-js');
    wp_enqueue_script('select2');
    wp_enqueue_script('animation-js');
    wp_enqueue_script('parallax');
    wp_enqueue_script('swiper');
    wp_enqueue_script('rebates');
}

But nothing works for me
