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

Design policy: White background + green rules. It does not assert itself by filling surfaces; instead it separates sections by standing a single green vertical rule to the left of section headings. Decoration is minimal, and instead the banners of product and dish photography carry the color. - About Mizkan: A food manufacturer of vinegar, Ajipon, Oigatsuo Tsuyu, natto (Kin no Tsubu), and more. The site houses corporate information and recipes (Ouchi Recipe) together, with the recipe side having higher information density. - Density: Medium to high. The top page stacks large banners + 4-column
