+//@function Calculates TEMA using triple exponential smoothing with compensator
+//@doc https://github.com/mihakralj/pinescript/blob/main/indicators/trends_IIR/tema.md
+//@param source Series to calculate TEMA from
+//@param period Lookback period for TEMA calculation
+//@param alpha Optional smoothing factor (overrides period if provided)
+//@param corrected Use diminishing alpha factors for each stage
+//@returns TEMA value from first bar with proper compensation
+//@optimized Uses exponential warmup compensator on all three EMA stages for O(1) complexity
