Mr. CHEESECAKE Style Design System (DESIGN.md, Japanese UI)

Design policy: Show through whitespace. One message per screen. The first view is a full-screen photo plus the logo only; the next section uses an entire screen for just a catchphrase and four lines of copy. - About Mr. CHEESECAKE: A cheesecake brand by chef Koji Tamura. "When can I buy it" is the core of the experience (sales two days a week, lottery sales, store exclusives), and the UI has many purchase-channel badges such as "Online Exclusive" and "Flagship Store." - Density: Low. Even as an e-commerce site, the grid is not packed tight. Product cards are in 4 columns, with generous spacing
