Nakagawa Masashichi Shoten Style Design System (DESIGN.md, Japanese UI)

Design policy: Worthy of a long-established craft shop — Japanese-style negative space, tranquility, and neatness. Eliminating decoration, dignity is expressed through whitespace and typeface contrast. - Density: Medium. A craft-catalog-like composition that carefully presents each product one by one. A layout with breathing room rather than information density. - Keywords: Neat, Japanese modern, craft, Yu Gothic, Mincho, Nara, long-life - Characteristics: All body text uses Yu Gothic (YuGothic). Noto Serif Japanese (Mincho) is mixed in for product headings, emphasizing the Japanese presence.
