Render a SwiftUI preview

Generate SwiftUI code from the most recent interaction context, render it to a PNG using ImageRenderer, and output it as a markdown image so it renders inline.

The "context" can take any form: a prose description ("show a profile card with a photo on the left and name above bio on the right"), an attached screenshot or mockup image, an ASCII layout diagram, or actual Swift code. Translate whichever the user provided into a single ContentView.

For example, this ASCII diagram:

+------------------+--------------------------------------+
|                  |           Name                       |
|                  +--------------------------------------+
|    Photo         |                                      |
|                  |           Biography                  |
|                  |                                      |
+------------------+--------------------------------------+

should become an HStack with the photo on the left and a VStack { Name; Biography } on the right, sized so the photo spans the full height. Match proportions and stacking direction faithfully; choose reasonable placeholder content (e.g. Image(systemName: "person.crop.square.fill"), sample text) when the input doesn't specify.
