   由 feed-ui.js 按环形偏移以内联 calc(var(--feed-figure-line) ± N×var
   (--feed-step-y)) 给出，上=上一个、中=当前、下=下一个）；智能体卡为定值
   尺寸（约为数字人帧的 2/3，不随帧放大；矮屏断点各自显式收缩），内部
   与边线均透明（卡位仅由图标+名称示意，
   透出底部画面），left 由 feed-ui.js 以 calc(var(--feed-agent-left) ± N×var(--feed-step-x))
   内联——步长按智能体卡宽计，中央卡左右两侧各露出大半张相邻卡（胶带头
   尾可见，可感知左右还有可选智能体）。竖条拖拽跟手平移 track、松手吸附
   切换、点击帧切换到对应数字人；横条中央卡高亮为选中项，点击卡切换
   （中央卡＝点击通话）。轻点中央画面即接听（手势处理在 feed-gestures.js
