   border-radius 时长在此单独声明，与调试点1/2完全独立；
   下方 JS 的 MORPH（启动延时）需与这里的时长保持一致（单位换算：.4s = 400ms）
   —— 柔和度相关（数值越小越淡、越大越朦胧）——
   --glow-line-color   光线本体颜色，降低 alpha 即整体变淡
   --glow-line-thickness 光线粗细
   --glow-line-softness  光线本体的羽化半径，越大越朦胧（这是"不刺眼"的关键）
   --glow-line-length    光线长度（0-50，占边框周长的百分比），越长越像柔和的拖尾而非亮点；
                         JS 会读取该值来计算「从起点抽出」这一段的时长，改这里即可，无需动 JS
   --glow-blur-color   外围柔光颜色
