/* 小红书对标图 · 样式
 * ===========================================================================
 * 视觉设定（改之前先读）：
 *   · 板块性格色 = **深墨 #22222A → #2C2C36** + **小红书红 #FF2442** 点缀。
 *     为什么用红：功能就叫"小红书对标图"，红色是这个平台最强的识别符号，
 *     一眼能认出来"这是干小红书的活"。
 *   · 🔴 **主行动按钮一律品牌橙 var(--primary, #f95901)** —— 站内铁律：主色不许换。
 *     板块可以有个性，动作色必须全站统一，否则用户找不到"该点哪个"。
 *   · 风险三档沿用站内体系：红（必须改）/ 琥珀（建议改）/ 绿（没问题）。
 *
 * 三条工程约束（本项目踩过，照做）：
 *   ① 含 position:absolute 装饰物的容器**必须自带 position:relative** ——
 *      否则装饰物按 right:-30% 溢出撑宽 document，手机端整页缩成 77%、右侧留白。
 *   ② 手机端底部要给固定 TabBar 让位（实测 74px 高，留 96px 稳妥）。
 *   ③ 数字列用 tabular-nums，否则字数/百分比那几列会跳。
 *   ⚠️ CSS 注释里禁止出现 "星号+斜杠" 序列（会提前结束注释，本项目踩过）。
