Design language comparison
Comet vs Hex
Both Comet and Hex commit to a dark-canvas approach, and they pair different display families (system-ui vs IBM Plex Sans). Beyond surface, motion divides them — Comet is expressive, Hex is subtle.

Palette & spacing overlap
Palette overlap is zero — Comet and Hex live in completely different chromatic registers, even when their layout grids feel adjacent. Their spacing scales overlap by 17% (8, 16 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.
Curator verdict
Pick a side. Mixing Comet's dark-first canvas with Hex's subtle motion vocabulary produces visual whiplash. Adopt one system as your primary, study the other for individual technique transfers (e.g. Comet's spacing, Hex's shadow).
