How to get URL to template directory in global namespace?

[Neo]

Working in the global namespace ( wire('page') ), I am trying to get the URL to the template directory to set the path for an image:

http://localhost/project/site/templates/images/loading-animation.gif

On a normal page, this would usually work with

$out .="<img src='{$config->urls->templates}images/loading-animation.gif' alt='Loading Animation'>"; 

In this case it does not: "$config->urls->templates" does not return anything and the full path of the particular page is loaded:

http://localhost/project/videos/page-title/images/loading-animation.gif

Would appreciate your guidance.

It's the same as wire('page')

wire('config')

Same goes for all PW variables (https://processwire.com/api/variables/)
