/* 手机端光晕修正：
   问题一：34vw 在 390px 手机上只有 133px 直径，blur(120px) 把它扩散成一圈极淡的雾，几乎看不见。
   修复：移动端改用 120vw 大球，让它真正填满整个首屏宽度，blur 扩散出来才有面积感。
   问题二：alpha 设计给桌面宽屏，手机小屏白底颜色更浓，要适度加深才看得见。
   问题三：overflow: hidden 在 .hero 上存在，光晕只能放在 .hero 外，或把 hero overflow 改掉——
           现在光晕球比 hero 大很多（120vw），溢出就被 .glow-field 的 overflow:hidden 截住，
           视觉上光晕依然来自那个角落，不会乱跑。 */
