+/**
+ * 列表卡片（走秀 / 街拍通用）。
+ *
+ * 标记沿用 look-grid.css 的 .showscard-* 系列——与 .snapscard-* 是成对定义、样式完全
+ * 相同的两套类名（见 look-grid.css 顶部注释），故统一用 showscard 不影响街拍视觉。
+ *
+ * 组件本身不接收「数据」prop：它被放在父级 <template x-for="it in items"> 内，由 Astro
+ * 在构建期内联为静态 HTML；卡片内的 Alpine 指令直接引用循环变量 it 与页面 Alpine.data
+ * 提供的方法（itemHref / cardTitle / cardMeta / getCardSlots / toAbsUrl / favState /
+ * toggleFav / SPIN_SVG）。两页只需各自在 extra 里实现 cardTitle / cardMeta / getCardSlots。
+ *
+ * 标题：cardTitle 始终渲染；cardMeta 为空字符串时整行隐藏（街拍用两行，走秀用一行）。

+/**
+ * 列表页（走秀 / 街拍 / 未来更多模块）共享的 Alpine 行为逻辑工厂。
+ *
+ * 设计动机：RunwayLooks.astro 与 StreetSnaps.astro 原先各有一份 ~400 行的 Alpine.data，
+ * 其中「加载 / 分页 / 收藏态校正 / 翻页滚动 / 卡片工具」等约 80% 完全重复，只有几处差异：
+ *   - fetch 调的接口与入参（selectedXxx）
+ *   - 收藏 type（'runway' | 'street'）
+ *   - 卡片标题 / 副标题 / 缩略图来源的格式化（gallery string[] vs images[]）
+ *   - 深链参数（?collection= vs ?city=）
+ *   - 骨架屏数量、翻页滚动目标容器
+ *
+ * 本工厂收口「不变的逻辑」，把「变的差异」通过 opts 注入，页面只保留自己专属的
+ * selected 变量 / pills / clearAll / 品牌弹窗等。新增模块 = 写一个 opts + 薄壳页面。
+ *
+ * 注意：Alpine.data 返回的是普通对象，无继承，故用 {...base, ...opts.extra} 做字段合并；
+ * 所有方法内的 `this` 在运行时都指向 Alpine 组件实例。
