Cursor vs PostHog
Cursor runs a dark-canvas system while PostHog chose light, and they pair different display families (ui-monospace vs Open Runde). Beyond surface, motion divides them — Cursor is subtle, PostHog is expressive.

Palette & spacing overlap
Their palettes share 10% 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 8% (12 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.

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