   - 原 line 6852-6873 是 7-10 v3 加的 override, 当时为了把演唱会橙色 kicker 改回紫色
   - 但 selector 是 descendant 没限定 scope, 同时覆盖到了 cover-overlay 下的 kicker
     · 主专栏 1+2 三张卡折叠态文字在 .home-showcase-cover-overlay 里 (白字 + text-shadow)
     · 旧 override 把 concert 的 kicker 改成紫色, h3 改成 #1f1a28 深色 + 1.15rem 字号
     · 跟 members/animation 的 cover-overlay 浮盖白字不一致
   - v14: 删除原 override, 让 concert kicker/h3 跟 members 完全一致
     · 继承 .featured-section--main .home-showcase-cover-overlay 通用白色样式
     · kicker: rgba(255,255,255,0.88), 0.7rem, 0.1em
     · h3: #fff, 1.55rem, 0.05em, ZCOOL XiaoWei 衬线, 500 weight
   - 保留: cover-overlay 通用规则 (.home-showcase-cover-overlay .home-showcase-kicker / h3)
   - 不影响: 音乐卡 (.home-showcase-card-music), 主专栏有 6, 7 个其他 cover-overlay 规则
   - 不动: cover-overlay .home-showcase-back-head 的 kicker/h4 (展开态) */
