9           Analysis:
10           - Background is a dark charcoal gray/black (#121212).
11           - The loader is an arc that occupies roughly 75% of a circle.
12           - It has a subtle "tapered" or fading edge look.
13           - The movement is a smooth, continuous clockwise rotation.
14           - The loader is positioned near the top-center of the viewport.
