A photography-first discovery system organized around the Pinterest Red CTA, the masonry pin grid, and a soft warm-cream chrome that gets out of the imagery's way. The home page is a content-discovery tool wearing the chrome of a magazine publisher: 70px display headlines, friendly Pin Sans typography, fully-rounded pill buttons (16px) on a cream-tinted neutral palette, and a sticky red "Sign up" CTA that anchors every viewport. Pin imagery is the system's load-bearing visual element — square, portrait, and landscape pins tile in a column-based masonry grid where each tile is a fully-rounded 16px-radius card, separated by tight 8px gutters. The chrome is otherwise quiet: warm grays, true whites, and a single saturated red — no decorative gradients, no atmospheric backgrounds, no shadows beyond a soft modal scrim.
