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

Palette & spacing overlap
Palette overlap is zero — Comet and Liveblocks 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 Liveblocks's rhythm provides the accent moments — pair them at section-level, not at component-level.
