Type Alias: TangentMode

TangentMode = "auto" | "linear" | "constant" | "free"

How a key's in/out tangents are derived. Persisted per-key so recording and neighbor-recompute can preserve a user's choice instead of forcing 'auto'. Mirrors Unity's tangent menu. (Defined here, not curveEval, so Keyframe can reference it without a circular import; curveEval re-exports it.)
