Palette & spacing overlap
Their palettes share 22% 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 67% (6, 8, 12, 16, 20 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.

Curator verdict
Pick a side. Mixing Obsidian OS's light-first canvas with Revolut Business's subtle motion vocabulary produces visual whiplash. Adopt one system as your primary, study the other for individual technique transfers (e.g. Obsidian OS's spacing, Revolut Business's shadow).
