<h1>类目侧栏常驻后，banner 轮播怎么摆？</h1>
<p class="decision">
已定决策：<strong>类目侧栏首页常驻左侧、不自动隐藏；头部不再随滚动收起；banner 保持 450px 高、左右裁切</strong>。
本页比较的是这 1200×450 黄金区域内的四种构图。四个方案共享同一份类目数据（6 个一级类目）与 3 张 banner，差异只在布局与信息层级。
方案 A 是上次讨论确认的方向，其余三个用于验证它是否真的是最优。

banner 只剩约 700px 宽。这是京东首页的经典三段式，<em>信息密度最高</em>，但 banner 被压缩得最狠。

banner 压到 300 高，侧栏保持 450 贯穿整个 hero；banner 下方的 150px 空隙用两张促销瓷贴填平。
<em>类目成为 hero 的视觉主轴</em>，banner 退居其次——适合把类目导航当核心入口的商城。
注意：这与已确认的"banner 保持 450"不一致，选它意味着推翻第 3 条决策。

<header><span class="num">D</span><h2>侧栏 + 双层 banner</h2></header>
<p class="thesis">
侧栏 450 不变，右侧纵向切成两层：主 banner 290 高（保持裁切策略），下面两张 160 高的活动位。
轮播仍是主角，但<em>首屏多承载两个固定营销位</em>，活动位的图不需要轮播、常显。

<b>我的建议：维持方案 A。</b>它零新增组件、与参考站一致、banner 面积最大；B/C/D 的额外营销位在当前 mock 阶段没有真实内容支撑，且 B/C/D 都以压缩 banner 为代价，与"优化 banner 轮播"的初衷相悖。
如果看完想改方向，告诉我选哪个（或组合，如 A + D 的常显位）；确认后我把最终决策写进 <b>pin-home-category-menu</b> 这个 OpenSpec change。
