Palette & spacing overlap
Their palettes share 6% of swatches at the dominant tier — a quiet signal both teams drew from the same neutral library before applying brand accents. Their spacing scales overlap by 50% (4, 8, 12, 16, 24 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.

Curator verdict
If you are building an interface that needs to reference both, Anthropic's restraint reads as the safer default and Clerk's rhythm provides the accent moments — pair them at section-level, not at component-level.
