“O. P. U. S.”是使用 FontVibe AI 创作的霓虹光效文字效果。青色与品红交替的圆润霓虹灯管大写字母，灯管芯明亮、光晕柔和，在黑暗中把彩色倒影投在湿地面上。

rendered as real bent glass neon tubes with visible tube brackets and mounting hardware. Bright cyan and magenta neon light, sharp glowing edges with soft light bloom, visible glass tube refraction. Slightly uneven brightness between letters for realism. Square 1:1. O. / P. / U. / S. stacked as a perfectly centered four-line vertical arrangement — each character and period on its own line — displayed as a real custom neon bar sign. Scene: aged dark brick wall background with subtle mortar texture. Letters in classic red-orange neon glass tubes with warm glow — visible mounting bolts and wire routing against the brick. Warm amber light bloom reflecting softly on surrounding brick surface. One letter slightly dimmer for realism. Classic American diner and bar sign aesthetic.
