“OPEN”是使用 FontVibe AI 创作的霓虹招牌文字效果。经典路边霓虹招牌：玻璃灯管在深色砖墙上发出暖粉与琥珀色光，带安装支架，湿地面上有倒影。

bright LED illuminated sign with clean modern glow — cooler, crisper than traditional neon. Electric blue-white LED light with sharp bright edges — more precise than warm neon tube glow. Each letter channel-lit from within, creating a clean backlit glow effect. The word "OPEN" large and dominant — maximum legibility from across a street. Modern LED sign aesthetics — the precision and energy-efficiency feel. Modern LED "OPEN" sign mounted in the window of a contemporary retail storefront. Crisp blue-white LED lettering glowing against the dark interior visible behind the glass. Subtle light spilling onto the floor inside, warm wood floors reflecting the LED glow. Rain-wet street outside blurring into bokeh in the background, headlights streaking. Cinematic 16:9 — the LED sign as a beacon of welcome in a dark rainy street setting.
