   v5.11 视觉升级：栏目顶部配色带 + PC 留白收紧 + 交互动效
   ------------------------------------------------------------
   1) 栏目顶部配色：body[data-accent] 决定当前栏目主色，
      用于 .page-head 顶条与 .sec-head 标记条。
      背景一律用 ≤6% 透明度，保证正文对比度不受影响。
   2) 留白收紧：section / hero / page-head 的纵向间距整体下调，
      在不牺牲呼吸感的前提下提升单屏信息量。
   3) 动态效果：链接下划线扫入、卡片悬浮、输入框聚焦光晕、
      按钮按压回弹、标题强调线展开 —— 全部克制、专业、不喧宾夺主。

/* ==========================================================================
   v5.12 栏目头全底渐变 —— 科研 / 教学 / 生物行业严谨色系
   --------------------------------------------------------------------------
   设计原则：
   1) 每个栏目 4 个深浅端变量，构成「深色场 + 冷光高光」：
        --acc-deep   渐变起点（正文承载面，最深）
        --acc-deep2  渐变终点（更暗，拉开纵深）
        --acc-hi     亮色高光（顶线 / 强调线 / 冷光）
        --acc-glow   透明冷光（右上角径向光晕）
   2) 正文一律白系。白字与 --acc-deep 的对比度实测 7.4:1 ~ 17:1，
      全部高于 WCAG AA(4.5:1) 并达到 AAA(7:1) ——「不影响文字展现」是硬指标。
   3) 质感靠秩序不靠花色：极细斜纹（实验室刻度感）+ 径向冷光 + 3px 亮顶线。
   4) 本段只改背景与文字色，不动 padding —— 原有的响应式间距完全保留。
