When I first tested STOP mode on the MCU (before adding any features), power consumption matched the documentation. But once I added peripherals and some functionality, it jumped to 370 µA.

After deeper reconfiguration of the MCU and peripherals before entering STOP mode, I brought it down to under 20 µA. Lesson learned: just enabling a sleep mode isn’t enough - extra tuning and clever hacks are essential for true low power.
