This is *not* the "essence of dCBOR.” There is *nothing* platform-specific in the motivation or specification of dCBOR, not for JavaScript or any other execution environment.

The motivation for numeric reduction is: to give the most common types of numeric values a *deterministic* serialization.

That’s it.

No more no less.

Please stop mischaracterizing.
