| /// The **`PerformancePaintTiming`** interface provides timing information about |
| /// "paint" (also called "render") operations during web page construction. |
| /// "Paint" refers to conversion of the render tree to on-screen pixels. |
| /// |
| /// There are two key paint moments this API provides: |
| /// |
| /// - (FP): Time when anything is rendered. Note that the marking of the first |
| /// paint is optional, not all user agents report it. |
| /// - (FCP): Time when the first bit of DOM text or image content is rendered. |
| /// |
| /// A third key paint moment is provided by the [LargestContentfulPaint] API: |
| /// |
| /// - (LCP): Render time of the largest image or text block visible within the |
| /// viewport, recorded from when the page first begins to load. |
| /// |
| /// The data this API provides helps you minimize the time that users have to |
| /// wait before they can see the site's content start to appear. Decreasing the |
| /// time until these key paint moments make sites feel more responsive, |
| /// performant, and engaging for your users. |
| /// |
| /// Like other Performance APIs, this API extends [PerformanceEntry]. |
| /// |
