ZOJIRUSHI (Zojirushi Mahobin) Style Design System (DESIGN.md, Japanese UI)

Design policy: A clean, spacious composition based on white, with brand blue #1d87d0 as an accent. CTAs are finished modestly as white pills (#ffffff background + #222222 text), while blue is used for "adding color to the space" such as nav tabs and decorative lines. A quiet elegance befitting a lifestyle appliance brand - Density: Body text line-height reaches up to 2.0, and brand copy is also a very relaxed 1.68. Heading letter-spacing is set wide at 0.05em, creating a composition that breathes through whitespace. Prioritizes the brand's atmosphere over information density - Keywords: Serene
