nosh Style Design System (DESIGN.md, Japanese UI)

Design policy: On a base of off-white (#fdfcfa), a single green #63a351 carries the entire action flow. CTAs are without exception full pills (border-radius: 9999px), and cards use 8px rounded corners. Food photography takes the lead, and the UI recedes. - Density: A product list with a lot of information is organized with 8px rounded cards and 4px-based spacing. Despite being a B2C e-commerce site, the density is close to that of a business UI. - Keywords: green, pill, 8px rounded corners, off-white, 4px grid
