10           - Background: Dark gray (#1a1a1a)
11           - Colors: 
12             Red: #a71a30
13             Blue: #163555
14             White: #ffffff
15           - Pattern: 3x3 checkerboard with white center
16           - Animation: 4 second loop. 
17             Every 0.5s the grid transitions between a "compact diamond" and an "expanded grid".
18             The rotation is continuous counter-clockwise.
