A show case of treating the script as HTML component. Script tag is used for
* passing the component parameters
* defining the position of component in DOM( right after SCRIPT tag )
The default script type="module" behavior
* prevents to run script type=module more than once
* does not set document.currentScript preventing the parameters passing and locating it in the DOM
embed-page enables document.currentScript use for above purposes as in non-module as in module type of scripts.
