“OPEN”是使用 FontVibe AI 创作的激光切割文字效果。粗壮无衬线大写字母从暖色桦木上激光切出，切口边缘焦黑、木纹清晰，凸立在深色胡桃木板上，琥珀色侧光。

Frosted or clear acrylic material: letter faces are smooth matte-frosted acrylic surface. Cut edges emit a continuous soft luminous halo — frosted acrylic glows white-blue-cool, clear acrylic creates prismatic edge-light along every kerf perimeter. With LED backlighting, edges are the brightest element. Minimal geometric bridge tabs on enclosed counters. The cut piece installed on a dark backing with backlight glowing behind. 'OPEN' laser-cut from frosted white acrylic, mounted on a dark near-black backing panel. LED backlighting emitting continuous soft white-blue glow from all cut edges. Installed in a modern minimal cafe window — warm amber interior bokeh background, dark night exterior visible. The edge-glow of the acrylic letters is the primary light source in frame. Wide 16:9.
