A ref stored as a property of a reactive object is unwrapped automatically, so obj.count returns the number. A ref stored inside a reactive array, or as a value in a Map or Set, is not unwrapped and still needs .value.
Template unwrapping has its own limit: only top level properties returned from setup are unwrapped. If setup returns an object containing a ref, writing the nested access in a template renders the ref object rather than the value. Assigning the ref to a local const in the template expression does not help either.
The practical rule is to keep refs at the top level of what setup returns, and to reach for shallowRef or a plain object when storing many refs in a collection. When in doubt, log the value in the template with JSON.stringify to see whether you are looking at a wrapper.
