Cle de Peau Beaute Style Design System (DESIGN.md, Japanese UI)

Design policy: Restraint and whitespace befitting luxury cosmetics. An "elegance of subtraction" that strips away decoration and expresses refinement through light and negative space - Density: Information density is low. Product visuals and white space take center stage, with text kept to a minimum - Keywords: Luxury, lightweight (300), warm cream, dark navy, restraint - Characteristics: font-weight: 300 (Light) is the overall keynote — wait, let me redo this properly.
