Palette & spacing overlap

Their palettes share 17% 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 58% (8, 12, 16, 24, 32 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.

Curator verdict

Pick a side. Mixing Luma's light-first canvas with Sierra's moderate motion vocabulary produces visual whiplash. Adopt one system as your primary, study the other for individual technique transfers (e.g. Luma's spacing, Sierra's shadow).
