Mix Appearance

Blends a to b using factor clamped to [0,1], rounded to the nearest transition step (ties upward). Resolution N produces at most N+1 weights, not a cap on authored swatches. Colour interpolation chooses OKLCH (default, shortest hue, chroma-reduced to sRGB) or linear-light RGB; distances stay linear in blocks. Endpoints are exact. Changed channels need explicit values on both sides or a concrete incoming default/lower layer. Nested XYZ fields are supported; palette workspace/byte limits apply.
