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

Design philosophy: A refined, restrained minimal design befitting a custom-order suit brand founded in 1927. Large-format photography and whitespace convey quality, while text is kept to a minimum - Density: Editorial style with generous whitespace. The hero is a full-screen photograph, and spacing between sections is wide. It balances the approachability that makes ¥33,000-and-up custom suits feel casual with the dignity backed by 100 years of history - Keywords: premium minimal, dark charcoal, muted colors, large-format photography, tailoring - Characteristics: - Two-font system: TT Commons
