A knob turn still wakes the chip (the RTC can't tell gestures apart), but the firmware now stays dark and checks the button: held while turning it boots at once; otherwise the ring glows for 2.5 s waiting for a click and goes back to deep sleep if none comes. Screen and Wi-Fi never start for an accidental nudge.
