/* ================================================================
 * 内容页共用组件（BEM 基础类）
 * ---------------------------------------------------------------
 * 用途：将 news-* / help-* / single-* / vip-* 四段中高度重复的
 *      "面包屑 / Hero 外壳 / 侧栏 Widget / 相关列表 / 联系卡片 /
 *       上下页导航 / 分区标题" 等结构抽取为可复用基础类。
 *
 * 用法（渐进式）：
 *   新页面 → 优先使用 .c-* 基础类；
 *   老页面 → 现有 .news-* .help-* .single-* .vip-* 段保留，
 *           不动其规则；如需微调仅新增自定义变量或修饰符类。
 *
 * 命名约定（BEM）：
 *   .c-block                → Block  基础组件
 *   .c-block__element       → Element 子元素
 *   .c-block--modifier      → Modifier 变体
 *
 * 主题变量：通过 --c-accent（主色）+ --c-accent-2（渐变副色）
 *   在组件外层覆盖即可切换配色，便于 news/help/single/vip 复用。
