This is a short, bright two-note chime with a metallic ring, lasting just over a second, like the signal heard before a subway announcement. It feels instantly familiar and urban, with a light, playful nudge that makes a scene feel busy and in transit. It draws on the classic New York City subway sound, so it places a listener on a platform without any extra explanation.
