PHP template files are compiled from the Compiler class.
However, the Resource compiler class Res is integrated with helper static methods that makes it easier
to render template files internally through the Compiler class.
These methods are discussed below:
Res::load() method. An example of this
is shown below.
Res::load('some-template', fn() => compile());
self::load() method. This is because the root source of
Window's self::load() comes directly from the Res Resource compiler class.
