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

Design philosophy: A premium outdoor/fashion brand that balances functional beauty with quietness. Eliminates unnecessary decoration, letting the product take center stage - Density: Compact. With a small base body size of 12px, it carries an editorial tension - Keywords: Serene, functional, minimal, premium, monochrome - Characteristics: Rather than pure black (#000000), it uses dark navy #001133 for all text. A "Quiet Luxury" visual composed almost entirely of two colors: white and navy. Even CTA buttons carry no color, using an extremely restrained design of white background + border
