UXP API: How to get Clip/ProjectItem Media Dimensions (Width/Height)?

Hello,

I need to get the source width and height of a selected timeline clip to accurately calculate anchor points.

Here is what I have tried:

1. Downcasting: Retrieved the ProjectItem base item from the clip and cast it using ppro.ProjectItem.cast(baseItem) to a ClipProjectItem.

2. Checking child objects: * clipProjectItem.getMedia() only exposes start and duration. clipProjectItem.getFootageInterpretation() exposes frame rate and PAR, but no resolution.

3. Metadata: Parsing ppro.Metadata.getProjectMetadata() streams is failing to capture the properties.

What is the officially supported UXP method to extract the asset pixel dimensions of a source item?
