Bug fix:desktop default .poster-stage 有 aspect-ratio:12/17 + overflow:hidden;
.poster-swiper 是横滑(overflow-x:auto + overflow-y:hidden)。在 mobile 这套
让 img 自然高(553)>stage(542)→ 底部被裁。
CSS 规范不允许 overflow-x:auto + overflow-y:visible 共存(后者会被强制 auto),
所以 mobile + paged 直接放弃页内横滑,改纵向堆叠所有页面,stage/swiper/pane
自然撑高;横向手势和侧边按钮专门用于切换 5 个风格。 */
