The frame parks in the middle and the colour changes instead: a gradient creeps round the colour wheel behind the poster, and the frame's glow travels with it. Every other animation moves the frame, so the still one reads as a rest between them rather than as a dead spot. The wash layer blends with mix-blend-mode: color, which keeps the poster's luminance and replaces only its hue. soft-light was the first try and barely shifted the colour at all against a poster already knocked back to 45% brightness.
