ref, bindings, events
Reactivity isn't "magic". Change `.value` on a ref and the template redraws itself.
ref(0) wraps a value. In the script you read and write count.value. In the template you don't need .value: {{ count }}. For an object people often use reactive({ n: 0 }) — the fields are reactive right away, without .value. Don't mix them without a reason.
