> `DAsyncContent` Render content that is loaded asynchronously. Give it a promise, a `TrackedAsyncData`, or a function that fetches the data via `@asyncData`, and fill the `loading`, `content`, `empty`, and `error` blocks; it reloads when `@context` changes, so there is no need to hand-roll loading flags and error handling.

This looks super promising. No need for a tracked loading var with a spinner anymore! Perhaps it’s time to update some components now.
