Profile Hunt: shadow-bird

You've been tasked with investigating a user who goes by the handle shadow-bird across multiple platforms. Intelligence suggests this individual has left digital breadcrumbs across the internet that reveal their hometown.

Your target recently posted the following message on a forum: "Just moved back home after 5 years abroad. Nothing beats the coffee at Ritual on Valencia Street, and the fog rolling over Twin Peaks every morning. Born and raised here, wouldn't trade it for anything."

Additionally, a reverse image search of their profile picture led to an old photography portfolio where they tagged several landscape photos. One caption reads: "Golden hour at the bridge, 37.8199° N, 122.4783° W — my favorite spot since childhood."

Your mission: Determine the hometown city where shadow-bird was born and raised. The flag is the city name in lowercase.
