Palette & spacing overlap
Their palettes share 5% 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, 4, 6, 8, 12 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.

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