shallowRef and Shallow Reactivity
shallowRef tracks only .value replacement, skipping deep Proxy conversion of the inner object, so large immutable-style data structures avoid per-property tracking overhead; updates require assigning a new object (or calling triggerRef), making it the performance tool for big lists, external state, and integration objects.
This Concept is waiting for its first lesson!
