 - 一级分类未选 18/w400、选中 20/w700；二级 chips 间距 10、左右 8、15/w600，并以稳定 AnimatedContainer 切换。
 - 首页内容区改为横向 PageView：点击与滑动共用 PageController，各 tab 保留纵向滚动位置。
+- PageController 与各 tab ScrollController 改为字段直接初始化，修复热重载后的 LateInitializationError。
 - 四类卡片去底板/描边，封面统一 3:4、8 圆角、行距 10、封底标题间距 6；状态角标为右上角紧凑异形丝带。
 - 标题下方恢复左对齐题材文字，使用 `|` 分隔、灰色小字，与封面状态角标保持独立。
 - 首页搜索栏到一级、一级到二级、二级到网格间距为 8/8/10；非精选 tab 直接以 10 衔接网格。
