Bluesky Mobile — design system & UI screens
A messaging interface showing a conversation thread with user profile (Eric, @esb.lol) at top, alternating blue and gray chat bubbles, and an embedded video player showing a concert/venue scene with neon lighting. Clean, minimal design with rounded message bubbles and timestamp indicators. Official Google Play listing screenshot.
