Vercel vs xAI
Vercel runs a both-canvas system while xAI chose light, and they pair different display families (Geist vs -apple-system). Beyond surface, motion divides them — Vercel is expressive, xAI is subtle.

Palette & spacing overlap
Their palettes share 15% of swatches at the dominant tier — a quiet signal both teams drew from the same neutral library before applying brand accents. Spacing scales diverge entirely — agents porting components from one to the other should expect to re-derive the ladder, not interpolate.

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