“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. A modern minimal café exterior at dusk: the frosted acrylic 'OPEN' sign glowing in the window with soft white-blue edge-light. Warm amber interior visible through the glass — customers at wooden tables, pendant lights, coffee equipment behind the counter. Cold blue twilight outside contrasts with the warm interior. The glowing 'OPEN' sign is the visual anchor of the entire composition.
