“STAY CALM”是使用 FontVibe AI 创作的日本水墨毛笔文字效果。把日本书道的水墨毛笔笔法用到拉丁字母上。浓黑的墨汁配上地道的毛笔笔势、单向可控的运笔，还有和纸的质感。做日料店品牌、纹身设计、动漫、武道和文化类项目都特别合适。

rendered in Japanese Shodo ink brush style. Letterforms painted with a loaded fude brush — deep sumi black ink with characteristic Japanese calligraphy energy. Visible individual bristle marks, confident single-direction strokes, ink density fading from wet-black core to dry-grey endings. Subtle washi paper texture visible. Shodo discipline — controlled power, intentional spacing, the beauty of ma (negative space). A matte grey ceramic Japanese teapot on a bamboo tea tray, steam rising from the spout. Beside the teapot: a small rectangular rice paper card standing upright in a miniature bamboo card holder, 'STAY CALM' written across it. The tray sits on a dark walnut table surface. A single warm amber overhead pendant light illuminates the scene. Background is deep shadow. The teapot and card share the center of frame. 9:16 vertical, traditional tea ceremony aesthetic.
