Very cool, it seems we almost came up with the same approach of components/templates. In your framework, it is referenced with a data-template attribute. In Reken, I use a data-component attribute.

One of the design goals for Reken was to not have to context-switch while coding, to not lose my train of thought (Guess my short-term memory is limited). Hence try to add everything inline in the HTML file. Also I'm working on a tailwind-like css inlining framework (compatible with Reken). Together these give me dynamic DOM and styling inline.
