Hakuhodo Brushes (Hakuho-do) Style Design System (DESIGN.md, Japanese UI)

Design policy: A monotone artisan aesthetic based on lacquer black #0f0f0f / #111111 on a pure white background. The hero uses a full dark surface (#0f0f0f) with white text overlaid, showing beautiful photographs of brushes at a large scale. Mincho (MS PMincho / serif) is used consistently throughout, with no gothic typefaces — the dignity of a long-established craft house - Density: A visual-driven layout that boldly uses product photography. Text information is sparse, with generous whitespace. Visual density is high (hero photography) but information density is low - Keywords: Lacquer black
