+// @function Calculates the Range Weighted Moving Average.
+//   Each bar's contribution is weighted by its range (high - low),
+//   giving more influence to volatile bars and less to narrow-range bars.
+//   RWMA = Σ(close[i] × range[i]) / Σ(range[i]) over the lookback period.
+// @param src Series to smooth (typically close).
+// @param high_src High price series.
+// @param low_src Low price series.
+// @param period Lookback window length. Must be > 0.
+// @returns The range-weighted moving average value.
