Palette & spacing overlap
Palette overlap is zero — Lovable and Spline live in completely different chromatic registers, even when their layout grids feel adjacent. Their spacing scales overlap by 75% (2, 4, 6, 8, 10 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.
Curator verdict
Pick a side. Mixing Lovable's light-first canvas with Spline's expressive motion vocabulary produces visual whiplash. Adopt one system as your primary, study the other for individual technique transfers (e.g. Lovable's spacing, Spline's shadow).
