/* ============================================================
 * 词元广场（QFAPI）— 沉浸式中转站 UI
 *
 * 配色（浅色是主设计，默认浅色；深浅色独立配置，不与其它页面共用主题键）：
 *   浅色：主 #ECB6C4（柔粉） / 从 #5EA2BA（雾青） / 末 #FEEDDF（奶油）
 *   深色：主 #242B36（墨蓝） / 从 #9C97B8（灰紫） / 末 #DCB8B7（干枯玫瑰）
 *
 * 结构：底色 + 柔光光斑 + 玻璃卡片；浅色像一张暖纸，深色像夜里的雾面玻璃。
 * 组件命名统一 qf-*；状态色（正常/异常/提示）另用 --qf-green / --qf-red / --qf-amber。
