Design language comparison
Comet vs Neon
Both Comet and Neon commit to a dark-canvas approach, and they pair different display families (system-ui vs GeistMono). Beyond surface, motion levels are both expressive.

Palette & spacing overlap
Palette overlap is zero — Comet and Neon 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
If you are building an interface that needs to reference both, Comet's restraint reads as the safer default and Neon's rhythm provides the accent moments — pair them at section-level, not at component-level.
