   DinoBlog V1.1 · 全站样式 css/style.css
   ----------------------------------------------------------------
   设计语言: 夜观 (dark-glass editorial)
   - 暗色(默认): 随机图 + 左右渐变黑遮罩(body::before) + 单一蓝点缀
   - 浅色: 白 + 磨砂玻璃 + 浅蓝; 两套主题变量完整对等
   - 可注入变量(:root 层, header.php 内联 :root{} 同特异性可覆盖):
       --accent --radius --font-size --font-family
   - 圆角规则: 卡片/面板 = var(--radius,16px), 输入件 = 10px,
       按钮与胶囊 = 全圆 999px (文档化的混合体系)
   - 动效基调: all .25s cubic-bezier(.16,1,.3,1); 仅 transform/opacity
   - z-index 刻度: bg -1 / nav 50 / u-pop 70 / mask 80 / drawer 85
                    dock 86 / panel 90 / toast 100
