Palette & spacing overlap

Palette overlap is zero — Anthropic and Realm live in completely different chromatic registers, even when their layout grids feel adjacent. Their spacing scales overlap by 58% (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 Realm's rhythm provides the accent moments — pair them at section-level, not at component-level.
