URL, file and upload.

Every media node takes either a URL or a page file. The inspector offers both, plus an Upload button that puts a file in the page store and points the node at it.

| Setting | Meaning |
| --- | --- |
| Fit | How the media fills its box — CSS object-fit. |
| Anchor | The focal point for cover and contain, e.g. 50% 50% or left top. |
| Poster / Still | A frame shown before playback starts. |

> **External URLs are a live dependency:** A graphic pointing at someone else's server fails on air exactly when their server does. Upload the asset to the page unless the URL is genuinely dynamic.
