Brex vs Comet
Brex runs a both-canvas system while Comet chose dark, and they pair different display families (inter vs system-ui). Beyond surface, motion divides them — Brex is moderate, Comet is expressive.

Palette & spacing overlap
Palette overlap is zero — Brex and Comet live in completely different chromatic registers, even when their layout grids feel adjacent. Their spacing scales overlap by 25% (8, 16, 32 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.
Curator verdict
Pick a side. Mixing Brex's both-first canvas with Comet's expressive motion vocabulary produces visual whiplash. Adopt one system as your primary, study the other for individual technique transfers (e.g. Brex's spacing, Comet's shadow).
