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

Design approach: As a fashion brand that embraces petite women, it balances elegance and approachability through a warm cream #faf7f2 surface and Optima Latin-script headings. Avoiding strong statements, it expresses "quality that blends into everyday life" through neutral earth colors. - Density: A relaxed product-showcase style. Product photography takes center stage, with text kept restrained. The wide letter-spacing of headings (0.2em) creates a sense of airiness. - Keywords: warm cream, Optima headings, earth colors, wide tracking, feminine, D2C fashion - Characteristics: - Dual font syst
