-/**
- * Calculates the [INP](https://web.dev/articles/inp) value for the current
- * page and calls the `callback` function once the value is ready, along with
- * the `event` performance entries reported for that interaction. The reported
- * value is a `DOMHighResTimeStamp`.
- *
- * A custom `durationThreshold` configuration option can optionally be passed to
- * control what `event-timing` entries are considered for INP reporting. The
- * default threshold is `40`, which means INP scores of less than 40 are
- * reported as 0. Note that this will not affect your 75th percentile INP value
- * unless that value is also less than 40 (well below the recommended
- * [good](https://web.dev/articles/inp#what_is_a_good_inp_score) threshold).
- *
- * If the `reportAllChanges` configuration option is set to `true`, the
- * `callback` function will be called as soon as the value is initially
- * determined as well as any time the value changes throughout the page
- * lifespan.
- *
- * _**Important:** INP should be continually monitored for changes throughout
- * the entire lifespan of a page—including if the user returns to the page after
- * it's been hidden/backgrounded. However, since browsers often [will not fire
- * additional callbacks once the user has backgrounded a
- * page](https://developer.chrome.com/blog/page-lifecycle-api/#advice-hidden),
- * `callback` is always called when the page's visibility state changes to
- * hidden. As a result, the `callback` function might be called multiple times
- * during the same page load._
