Blue U.S. passport found near River Walk

I found a blue U.S. passport this afternoon around 2:30pm on the sidewalk outside the Starbucks by the River Walk near the Arneson River Theatre in San Antonio. The cover is the usual dark blue with the gold seal, a bit worn from travel, and the corners are slightly creased. There's a tiny coffee stain on the back and a small dent along the bottom edge. I know how important this is for the person it belongs to, and I want to help get it back to them—if you think this might be yours, share a detail that only you would know from your passport so we can confirm ownership.
