I'm talking about visual similarity with an actual physical chain link.

I'm thinking of it as "the pre-existing (prototype) properties go
before the new (own) properties", in other words the spatial and
temporal order of the properties matches.

True, and it also looks like a diamond which some might associate with
multiple inheritance. A better "prototype chain" analogy might be ><
since the operands themselves would then serve as the chain links
being linked together...
let B = A >< {
...
};
However, I agree with your comment in another post that contextual
keywords are worth considering even though they introduce restricted
productions. If we were to go that route, I would propose:
// replace <| with "prototypes"
let B = A prototypes {
...
};
// replace <& with "owns"
let b = B owns {
...
};
Thanks,
