 The `useProfiler` hook tracks `ui.react.mount` and `ui.react.render` spans. It does not track `ui.react.update` spans. If you need update tracking, use [`withProfiler`](#withprofiler-higher-order-component) or the [`Profiler` component](#profiler-component) instead.

 The `Profiler` component accepts the following props: `name`, `disabled`, `includeRender`, `includeUpdates`, and `updateProps`. Pass `updateProps` to enable `ui.react.update` span tracking — when the values in `updateProps` change between renders, the Profiler will generate update spans. This is the main advantage of using `Profiler` over `useProfiler`, which does not track updates.

 `withProfiler` handles `updateProps` automatically by forwarding the wrapped component's props. When using the `Profiler` component directly, you need to pass `updateProps` yourself.
