UNIQLO Japan Style Design System (DESIGN.md, Japanese UI)

Design policy: A global design system for large-scale e-commerce. Body text and headings use a slim (font-weight: 300) + solid setting (beta-gumi) minimal typography, making product photos and prices the stars - Density: Product-grid-centric with relatively high density. However, whitespace is handled carefully, resulting in a calm composition where only the red of prices and black buttons serve as accents - Keywords: Minimal, Photo-First, Light Weight, Square Corners, Enterprise
