Vaashu Zip ((new)) 📢

Note: because "Vaashu Zip" is not an established mathematical object or standard term in the literature, I will treat it as a definable construct and develop a coherent, rigorous theory around a natural abstraction suggested by the name. I define Vaashu Zip as an operation on sequences (or indexed sets) that "zips" together components with a structural twist, then prove a precise property about it.
