Oreo (1912) rebuilds the world's most recognizable cookie as a UI system: two cocoa-black wafers, a disc of white creme, and that famous embossed rim. The 90 edge ridges, four-petal florets, and raised-relief stamping become buttons, cards, and dividers — everything pressed into dough, not printed onto paper. It lives strictly in cocoa-near-black and milk-white. No color negotiates for attention; the tension between the two poles is the entire design, and motion borrows the ritual — twist, lick, dunk.
