产品广告｜Wabi-sabi matcha launch poster

原始提示词（待中文全文翻译）： Design a 1:1 vertical poster for a new ceremonial-grade matcha launch. Brand name: "Kumo Matcha". Style: contemporary wabi-sabi, restrained, quietly confident. Colors: soft moss green, unbleached linen, charcoal, a whisper of gold leaf. Use washi paper texture, broad negative space, a single sumi-e brushstroke as a compositional anchor. Center subject: a stoneware chawan with freshly whisked matcha, fine foam on top, a bamboo chasen resting beside it. Poster must cleanly display: brand mark, product name, grade (Ceremonial · First Harvest), tasting notes (umami, fresh grass, stone fruit), origin (Uji, Kyoto), suggested preparation, launch date, limited-batch number, and a small QR module. Elegant not cheap, typography hierarchy clear, small numerals and Japanese characters rendered accurately
