“千极之径”是使用 FontVibe AI 创作的霓虹描边文字效果。空心描边大写字母，只由一条发光的蓝紫霓虹线勾出，内部漆黑，外有柔和光晕和亮面地面倒影。

Pure neon outline letterforms — each letter defined only by its glowing stroke border, interior completely hollow and dark. The outline stroke glows with a continuous tube-light energy: bright white-hot center line along the stroke path, vivid neon glow zone expanding outward, soft wide halo bleeding into surrounding darkness. Glow is wider on the outside edge of the stroke than the inside, following real gas-tube light physics. Interior of each letter reads as deep void — no fill, no ambient light bleed inward. Stroke width is crisp and consistent, geometric precision. Slightly uneven brightness variation along the stroke path for organic gas-tube character. Choose neon color based on text meaning and mood: electric blue + deep violet for tech/cyber/cold words, neon pink + magenta for vibrant/pop/fun words, lime green + cyan for acid/gaming/matrix words, warm amber + orange for retro/diner/warm words, or multi-color with each letter a different hue for festive/creative content. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters, rendered as their glowing hollow outline; this style governs the gas-tube glow physics and the color. FALLBACK MATERIAL: if the font carries no material of its own, render each letter as a pure hollow glowing neon outline with a white-hot center line, outward glow and a dark void interior. COLOR PRIORITY: keep the font's own colors if specified; otherwise choose the neon hue by the word's mood (electric blue/violet for tech, pink/magenta for fun, lime/cyan for gaming, amber for retro). 「千极之径」四个汉字以霓虹空心轮廓呈现——每个字符仅由发光描边构成，笔画内部为深邃虚空，无任何填充。描边发出冷冽的霓虹光：笔画路径上有明亮的白热中心线，光晕向外侧不对称扩散，外缘光晕宽于内缘，严格遵循真实气体放电管的发光物理规律。字符笔画交叉处光晕略微叠加增亮，转角处白热点稍强，为发光管增添有机感与呼吸感。整体色调选用冷调蓝紫——主体描边为高饱和电光蓝，外缘光晕过渡为深紫罗兰，呼应「径」（路径/旅程）与「极」（极致/极限）的冷峻意境。背景为深夜大气渐变：顶部近黑的深靛蓝，向中部过渡为幽深的午夜靛紫，底部收敛为近黑炭灰，绝非纯黑——空间中漂浮着霓虹散射产生的极淡冷光微粒，大气中有隐约可见的蓝紫色光雾。画面下方四分之一处有一条几乎隐形的光滑地板反射面，湿润的黑曜石质感，将四字的发光描边向下映射为逐渐消融的色柱倒影。文字四周保留大量沉默的暗空间，文字约占画幅宽度的60%，周围的静默本身即是设计的一部分。整体氛围：高度冷感、精密、深邃，如深夜山间无人之径.
