/*! * NaFNav · 分类页组件层 * --------------------------------------------------------------------------- * 覆盖三类归档模板：网址分类（favorites / sitetag）、 * 应用分类（apps / apptag）、书籍影视分类（books / booktag / series）。 * * 一套骨架，三套卡 * ----------------- * 三个分类页的页头、子分类、筛选条、分页、侧栏完全同源，差异只留在 * 卡片体（.tx-site / .tx-app / .tx-book）。改版前的网址分类走主主题的 * io_get_taxonomy_head_html()（分类缩略图当背景、文字浮在图上）， * app/book 分类走子主题的另一套 .ab-hero —— 两套页头毫无关系， * 用户在三个分类页之间切换会觉得像换了站。 * * 分层：只消费 sub-base.css 的语义层令牌（--naf-surface-* / --naf-text-* / * --naf-accent-* / --naf-space-* / --naf-radius-*），不新增原始色值。 * 命名：.tx-*，与 sub-home（首页）、sub-app-book（应用/书籍详情与旧列表） * 命名空间分开，避免样式互相踩到。 * * 单一来源 * -------- * 本文件是唯一来源。设计稿由 tests/render-taxonomy-preview.php 调用 * 真实渲染函数产出，内联的就是本文件 —— 改样式与改设计稿是同一件事。 * * 骨架 * ---- * 0. 局部变量 * 1. 分类页外壳与页头 .tx-hero / .tx-emblem / .tx-title * 2. 子分类磁贴 .tx-subs-grid / .tx-sub * 3. 筛选工具条 .tx-chips / .tx-chip / .tx-sort / .tx-view * 4. 卡片网格 .tx-grid--site / --app / --book * 5. 共用零件（徽章等） * 6. 空状态与骨架屏 * 7. 侧栏 * 8. 分页 * 9. 响应式 * 10. 暗色与高对比度 */.nafnav-tax{--tx-gap: var(--naf-space-4);--tx-emblem-a: var(--naf-teal-700);--tx-emblem-b: var(--naf-teal-500)}.nafnav-tax--app{--tx-emblem-a:
