The mark is now a hex-meshed cube in isometric view whose faces carry a banded colour fringe (blue to red, hottest at the front corner), with three tapered streamlines wrapping around it. The small variant keeps the fringe cube and one bolder streamline. Icon Composer gets four groups (floor, flow behind, cube with mesh, flow in front), its maximum. The title-bar mark is redrawn as the fringe cube. Co-Authored-By: Claude Opus 5.5 <[email protected]>
