/* ======================================================================
 * GV11 · 工具站新视觉基座（2026-11 重设计）
 *
 * 与旧的 tool-detail.css「亮蓝+纯白」彻底换轨：
 *   配色：暖纸面 #F5F4EF / 墨绿文字 / 玉绿主色 / 琥珀点缀；深色用松墨底 + 薄荷光
 *   布局：首屏为「标题带 + 实时读数带」，工作台左右分栏，结果列桌面端吸顶
 *   字体层级：Display 46 / H1 30 / H2 22 / H3 16 / Body 15.5 / Caption 12.5，
 *             正文行距 1.9，数字统一 tabular-nums
 *   主题：跟随导航 #themeToggle 写入的 html[data-theme="dark"]，页面内不放开关
 *   作用域：全部选择器限定在 .gv11 内，不影响站内任何既有页面
 * ====================================================================== */
