   結構（由 js/card.js 產生）：
     .card                         外殼：階級／陣營變數、進場錯開
       .card-aura                  卡片背後的階級色光
       .card-3d                    3D 傾斜（--rx / --ry 由 fx.js 寫入）
         .card-flip                翻面（.card.flipped → rotateY 180）
           .card-face.card-front   正面：立繪＋名牌＋預覽
           .card-face.card-back    背面：六維雷達＋數值
   所有動畫預設靜止，hover／focus／.live 才播放，200 張卡也不會燒 GPU。
