/**
 * 全站版面壳：页面画布与内容区布局
 *
 * 默认（rail）：斜纹页底 + 双侧竖轨白底版心；类名 .wa-index-page
 * 备选（blocks）：平铺底、通栏分区边线；加 .wa-index-page--blocks
 * 快速预览：?layout=blocks|rail ，或导航版式图标 / WA_CHROME.setLayout(...)
 *
 * - 通栏导航条带（.wa-nav--bar）两套共用
 * - 页头 / 分区跳转 / 关注 CTA / 版心页脚
 * 导航控件本体在 components.css；本文件只管版面骨架。
 * Token：var(--wa-*)；勿运行时引用 frame/
 * 圆角分层：卡/面 --wa-radius · 大面/强调块 --wa-radius-lg · 轻控件 --wa-input-radius ·
 * 大钮 --wa-btn-radius-lg；胶囊形（chip/圆钮）固定 999px（形，非表面阶）
 * 矮条/小方钮（关注 CTA）对 token 封顶，避免大圆角品牌皮收成胶囊
