Gray ceramic mug with blue interior and heart on handle

I lost my gray ceramic mug with a blue interior yesterday around 3pm near the Stockton Central Library on Weber Ave. It's a small mug, about 3.5 inches tall, from a local cafe called Morningside Roasters, with a tiny red heart painted on the handle and a faint coffee stain on the bottom. It has sentimental value—my grandmother gave it to me before she passed, and I use it every morning. If anyone found it, I’d really appreciate getting it back; I’m hoping it's tucked somewhere around the library steps or the bus stop by Weber Ave.
