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 58% (4, 6, 8, 12, 16 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.

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