The Wow Moment
You grab a mango at the grocery store and see the sundial sticker at 6 o'clock — vibrant orange. You know instantly: eat within 24 hours for peak sweetness. The clerk next to you watches you pick three perfect mangoes in 10 seconds while they're still squeezing and guessing, and asks where you got your 'magic stickers'.
