GREEN SPOON Style Design System (DESIGN.md, Japanese UI)

Design policy: Natural, warm, refined food & lifestyle - Density: Relaxed media type. A composition that makes the most of large visuals and whitespace - Keywords: Warm Ivory / Natural Green / Editorial Food / Lifestyle Luxury / Handcrafted Feel - Characteristics: A Japanese-Western mixed typesetting that uses an English display font (Riviera) for headings and composes body text in Yu Gothic. The entire page is unified in a warm ivory (#fbfbf6), and pure white is not used. Color-coding for each food ingredient category is a distinctive feature
