Glow is how much life ATOM shows. Settings > Look and feel > Glow.
CALM (the default): buttons catch a soft light when you point at them, clickable cards lift a little, the screen you're on glows in the left menu, and toasts spring up. Real finish lines get a small sparkle: a settlement landing, the last per diem signed, an advance reaching 100%, approving a whole guest list, a hotel import, finishing setup. Today on the tour calendar breathes a slow glow, and on show day the ATOM mark in the top bar glows.
ALIVE: everything in Calm, plus slow drifting color behind page headers and a bigger sparkle.
OFF: everything holds still. Colors stay the same. Home's Reduce motion button is this same switch.
YOUR DEVICE WINS: if Reduce Motion is on in your iPhone or Mac settings, ATOM stays still whatever you pick here.
IT FOLLOWS YOUR LOGIN: pick it once and your phone, laptop and Mac app match.
WHERE IT NEVER GOES: nothing moves behind numbers or text you read, nothing flashes, and Money gets no glow except the moment a settlement lands. Printed day sheets and PDFs never carry any of it.
