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% (2, 6, 8, 10, 12 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 ReadMe's expressive motion vocabulary produces visual whiplash. Adopt one system as your primary, study the other for individual technique transfers (e.g. Obsidian OS's spacing, ReadMe's shadow).
