### Thermal Guard Configurations
* **Woofer Thermal Guard (`thermal_guard` @ Post-`wlim`):**
* **Continuous Power Cap:** **$500\text{ mW}$ ($0.50\text{ W}$)** per channel ($8\%$ of max $6.25\text{ W}$ peak power).
* **Linear RMS Threshold (`al`):** `0.282843` ($-10.97\text{ dBFS}$ RMS).
* **Continuous Power Cap:** **$1.0\text{ W}$ ($1,000\text{ mW}$)** per channel ($16\%$ of max $6.25\text{ W}$ peak power).
* **Linear RMS Threshold (`al`):** `0.4000` ($-7.96\text{ dBFS}$ RMS).
* **Heating Tau ($\tau_{\text{heat}}$):** $2,500\text{ ms}$ (2.5 seconds).
* **Cooling Tau ($\tau_{\text{cool}}$):** $5,000\text{ ms}$ (5.0 seconds).
* **Tweeter Thermal Guard (`tweeter_thermal_guard` @ Pre-`tlim`):**
