9           Analysis:
10           - Background: Dark charcoal gray (#2c2c2c).
11           - Container: A white square with slightly rounded corners.
12           - Liquid: A soft blue (#bcd9f5) that moves with a rolling wave motion.
13           - Animation Technique: A large, slightly rounded square rotating inside an overflow-hidden container.
14           - Timing: Approximately 4 seconds for a full 360-degree rotation cycle.
