Happy to see HyperTalk-inspired innovation on the web! It looks cool. How did you decide what verbs and nouns to support? Also, thanks for the twinge of HyperCard nostalgia you gave me!
the verbs are largely ad-hoc, using HyperTalk as a jump off and then trying to think about how to modify the language for the DOM (e.g. CSS literals) and simplify things for script writers (e.g. async transparency)
