Root object of the path.
Dot-separated property path; must be non-empty.
Optionaladapter: ValueAdapter<unknown>
Pre-typed adapter, skipping detection. Supply it when the
value type is known statically, when the property is currently null, or to
disambiguate a four-number array (see detectAdapter). No check is
made that it matches the current value: this is the "typed property
reference" form of §16, where the caller owns the type.
Resolves
pathagainsttargetonce and returns a binding for the property it names.pathis dot-separated ("opacity","transform.position"). Every intermediate segment must already resolve to an object, and the final property must exist on its owner — inherited accessors count, so a getter or setter declared on a prototype binds fine.
