A Minute Brown Scavenger Beetle (Latridiidae), probably Melanophthalma. With a grain of coarse sugar.
I usually put some descriptor in the search box; "tiny brown beetle", for example. And BugGuide takes its time, and gives me thousands of brown or black beetles, and a few things that aren't beetles at all. This time, I used the size: "beetle 2mm". And the match to mine came up immediately, on the first lot of photos.
Something to remember for next time.
