It matches the trunk's materials and was lying loose back there but I
cannot figure out where it belongs or what it is.

Kinda looks like an under-dash panel to me.

looks like the shelf in the glove compartment

Thank you, sir! That's it. It fits like a glove (pun intended)
and greatly improved the use of the cavernous glove box.
The prior owner wanted that enormously huge, War and Peace
sized owners manual in there instead.
I appreciate it.

no worries, happy to help

My war and peace fits in the GB even with the shelf in place. I carry it because it seems I am always forgetting how something works and asking the DW to look it up while we are traveling down the road. Where are you in Arkansas?
