+ * 外观偏好同源读代理（oapi 代理轮 2026-10-08，全端统一形态）。
+ *
+ * <p>浏览器（通道 init 异步段）只与本应用【同源】取数——CAS 会话天然有效，无需 iframe 引导；
+ * 后端经 open-gateway 签名直调 UserHome（target=userhome，寻址走 yh.open.services，
+ * 勿写死 host）。设置入口收敛在 UserHome 设置中心，本端点【只读不写】。</p>
+ *
+ * <p>契约 = UserHome /oapi/appearance 出参【整体透传】（JsonNode 哑管道）：字段加减只在
+ * UserHome + 通道 init 两端演进，本应用零改动。现行字段 {@code {theme, avatar, logoUrl}}——
+ * theme/avatar 为服务端合成后的【生效值】（个人→学校→平台级联，不拆 my/sch）；
+ * null=未配置，init 侧清对应本地键回落默认观感。</p>
+ *
+ * <p>降级铁律：UserHome/网关不可达时【必须】以非 2xx 返回（503），绝不能伪装成 200+全 null——
+ * init 会把全 null 收敛成清键，等于 UserHome 停服一次就清空全员本地观感。</p>
