/*
 * QKYone 主样式 v3
 * ------------------------------------------------------------------
 * 设计目标：简洁、大气、科技感。参照同类 SaaS 企业官网的版式节奏，但
 *          视觉语言与内容全部为企开元自有，不复制任何外部素材。
 *
 * 三条硬约束（与改版方案一致，勿破坏）：
 * 1) 首页不做「登记信息公示板」：公司主体字段、官方域清单只出现在页脚、
 *    /about/ 与「公司信息」页模板，不占用首页首屏与视觉主舞台。
 * 2) 颜色对比度满足 WCAG 2.1 AA：正文 ≥4.5:1，大字 ≥3:1，装饰元素不作为信息载体。
 * 3) 移动优先，320px 起可用；触控目标 ≥44px；无横向溢出。
 *
 * 断点：480 / 768 / 1024 / 1280
 * ------------------------------------------------------------------

 * 根因：内页 .entry-content 被 max-width:46em（736px）整体限宽，而

 *       左侧约 63%，右侧长期空出约 424px；标题与面包屑是满宽，正文
 *       却是窄栏，两者宽度也对不齐，整页视觉重心偏左。
 * 处置：内页改「正文 + 右侧栏」双栏，沿用文章页 layout-with-sidebar
 *       的同一套栅格语言（1fr + 300px / gap 64px）。左栏正文保持 46em
 *       阅读行宽，表格与卡片栅格等结构件放行到左栏满宽；右栏承载站内
 *       导航与联系方式，使 1160px 内容区被完整利用。
