Palette & spacing overlap
Their palettes share 29% of swatches at the dominant tier — a quiet signal both teams drew from the same neutral library before applying brand accents. Their spacing scales overlap by 58% (4, 8, 10, 12, 16 px shared) — a rhythm any agent can transfer between the two systems with minimal recalibration.

Curator verdict
Pick a side. Mixing Mistral's light-first canvas with PromptWatch's moderate motion vocabulary produces visual whiplash. Adopt one system as your primary, study the other for individual technique transfers (e.g. Mistral's spacing, PromptWatch's shadow).
