 * ②号子屏幕 · 记忆快捷功能区（2×2 快捷入口，含「记忆管理」）独立样式
 * ---------------------------------------------------------------------
 * 位置：原「单张拍立得」组件所在区域（②号屏「闲置」快捷区横带下方的右侧）；
 *       本组件按 order 22 注入，排在快捷区（20）与心域入口（21）之后；
 *       快捷区经 sub-screen-2-shortcuts.css 的 position:relative+top 纯视觉下移，
 *       与本组件同一水平带（左快捷区 / 右记忆区），精神领域保持原位不动。
 * 尺寸：对齐 sub-screen-2-shortcuts.css 的 2×2 规格（70×70 + 12px 间距）。
 * 主题：默认浅色玻璃；暗色模式与不支持 backdrop-filter 的内核均有兜底。
 * 命名：统一 ss2mm- 前缀，独立文件，不与其它屏幕/组件共用样式。
