Consider how to display complex geometry in map inset

The map inset will show both the geometry and the bounding box. If they represent different shapes, they appear on top of each other. Example: https://geodev.btaa.org/catalog/camel-1006400

Would it be possible to use a different color for the geometry overlay? With some explanatory text? Just brainstorming here on making this more intuitive....

Circling back to this - for an upcoming article, I am planning to document some examples on how the complex geometry is useful. The case might be stronger if the bbox looks different from the geometry polygons. A few candidates I might use:

For complex geoms, we could style the bbox like so:

We have a lot of control here: color of the line, solid vs. dashed, etc. In the screenshot above, I've made it a dashed line with the same color as the geojson polygon.

Looks good.
