 "symptom": "Off-grid wake-cycle camera. (1) machine.deepsleep() with RTC.wakeup(60000) always came back at ~61-62 s regardless of USER presses (two runs) or a PWR press. (2) machine.lightsleep(60000) with a Pin.irq on SW never returned: USB dropped after 2 s, an LED left on stayed on past the minute, no code after the call ran, power cycle needed. (3) Polling the button at each wake instead: a machine.Pin(SW, IN, PULL_UP) created at module import read 1 (released) on every wake while the button was held, but the same read from the REPL a second later gave 0.",
