You fill it with everything you want to say — photos, voices, videos, even documents — and decide when each one opens: up to 10 dates, each sealed until its day. For the 18th birthday. For the wedding. For every year still to come. The frame stands in view the whole time — and opens again and again, moment by moment, when the day arrives: you hold your phone to the frame, and there is your voice, your picture, from back then. The frame is the key — only whoever holds it can open it. No link to forward, no second copy. A promise that keeps being kept, year after year.
