Museum of Contemporary Art Tokyo (MOT) Style Design System (DESIGN.md, Japanese UI)

Design policy: Artworks and exhibition visuals are the stars; the UI is an achromatic frame. Surface colors, rounded corners, and shadows are barely used; layers are built from black, white, and light gray alone, with color entrusted to the exhibition key visuals - About MOT: As a public museum, it must balance its duty to provide information (opening status, admission fees, accessibility) with the experimental spirit of a contemporary art museum. The result is a structure of "a permanent opening-status band at the top" + "a full-screen exhibition gallery" - Density: Medium to high density. Th
