Pass variable from theme page template to commerce-product file
You can use the next function in your theme / module:

function YOURT_HEME_preprocess_commerce_product(&amp;$variables) {
 $variables['product_cta'] = 'Static Text';
}

function YOURT_MODULE_preprocess_commerce_product(&amp;$variables) {
 $variables['product_cta'] = 'Static Text';
}


And show the variables in the commerce-product.html.twig file:

{{ product_cta }}
