Palette & spacing overlap
Palette overlap is zero — Cal.com and Lovable live in completely different chromatic registers, even when their layout grids feel adjacent. Their spacing scales overlap by 92% (2, 4, 6, 8, 10 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, Cal.com's restraint reads as the safer default and Lovable's rhythm provides the accent moments — pair them at section-level, not at component-level.
