/* ==========================================================
 * 新增页面类名适配层（tools.css 内）
 * ------------------------------------------------------------
 * 背景：站点既有页面使用 .navbar/.nav-inner/.nav-links、
 *       .footer/.footer-grid/.footer-col、.section-head、
 *       .grid/.grid-3/.grid-4、.card、.feature-card、
 *       .faq-list/.faq-item、.data-table 等既有类。
 *       本轮新增页面（计算器/裂变/口碑墙/博客）最初按通用命名书写，
 *       为避免改动既有页面，这里提供「别名映射」：
 *       新页面用的类名 → 复用站点既有样式，视觉与全站完全统一。
