Telegram Appearance Picker Illustration Animation

In Telegram's appearance settings, users can scroll through a horizontal carousel of chat themes. Tapping a theme card smoothly moves the selection border to it. Simultaneously, the custom vector illustration inside the selected card plays a delightful, unique micro-animation (e.g., a chick wiggling, a snowman jumping, a heart beating). The chat preview above dynamically transitions its background pattern, bubble colors, and accent colors to match the selected theme, providing instant visual feedback.
