Conclusion
We can easily specify default values for props in Nested.svelte:
Nested
<script>
let { answer = 'a mystery' } = $props();
</script><script lang="ts">
let { answer = 'a mystery' } = $props();
</script>If we now add a second component without an answer prop, it will fall back to the default:
App
<Nested answer={42}/>
<Nested />previous next

<script>
import Nested from './Nested.svelte';
</script>
<Nested answer={42} />
