Comet vs ReadMe

Comet runs a dark-canvas system while ReadMe chose light, and they pair different display families (system-ui vs ui-sans-serif). Beyond surface, motion levels are both expressive.

Palette & spacing overlap

Palette overlap is zero — Comet and ReadMe 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 ReadMe's expressive motion vocabulary produces visual whiplash. Adopt one system as your primary, study the other for individual technique transfers (e.g. Comet's spacing, ReadMe's shadow).
