Palette & spacing overlap
Their palettes share 9% 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% (4, 8, 12, 16, 24 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.

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