Here's a fact worth sitting with: a lit phone screen in a dark auditorium can be visible dozens of rows away—the contrast, not the intent, does the distracting. My opponent says a staff-accessed pouch handles emergencies. But how quickly can staff reach row 14 in the dark, find the right pouch, and unlock it while the film runs? If the policy needs a human exception every time, hasn't it just moved the friction rather than removed it? I'd still ask which target is more reliable: the glowing behavior, which an usher can address in seconds, or every phone, locked on the chance someone forgets it's there?
