/* ===== PC 顶部夜间切换入口（v18：注入到 .header-banner-right 内、搜索框 .top-search 之后，作为独立兄弟节点） =====
   v24：去掉灰色圆形底 + box-shadow，间距从 0 10px 缩到 0 4px，参考 7b2 自带图标风格（纯线性图标，无背景圆）
   v25：参照 7b2 .change-theme button 标准盒子（24×24，icon 22px）进一步对齐：
        · 盒子缩到 24×24（与 ⊕🔔 button 同尺寸，不再 32×32 显空）
        · SVG 缩到 20px（接近 i 22px 视觉重量）
        · margin 归零：左 16px 由父主题 .social-top .top-search{margin-right:16px} 自然提供；
                       右靠 social-top .change-theme{margin:0} 自然贴紧 ⊕ —— 视觉节奏与 ⊕→🔔 一致。
   v31：高度 24 → 34，与父主题 .login-button button.empty（padding 5 + line-height 22 + border 2 = 34）一致；
        让 SVG 视觉中心和登录按钮文字中心在同一条水平线上（v30 反馈"不在一个水平"）。 */
