Palette & spacing overlap
Palette overlap is zero — Lovable and Mercury live in completely different chromatic registers, even when their layout grids feel adjacent. Their spacing scales overlap by 67% (4, 8, 12, 16, 20 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 Mercury's moderate motion vocabulary produces visual whiplash. Adopt one system as your primary, study the other for individual technique transfers (e.g. Lovable's spacing, Mercury's shadow).
