Per-point colour encoding — { column, range }: map the column's finite
extent linearly onto a two-stop colour ramp [atMin, atMax] (interpolated in
sRGB). A point whose colour column is non-finite falls back to the base colour
(the single styling channel — theme.scatter[as].color).
Omitted ⇒ the base colour for every point. The range stops must be CSS
hex (#rgb / #rrggbb); a non-hex stop disables interpolation for that point
(falls back to the base colour) rather than guessing.
