/* body是display:flex+flex-direction:column(見上)，#GameDiv是唯一的flex item，預設flex-shrink:1——
   手機軟體鍵盤彈出時，body的實際box高度會被瀏覽器/WebView真的壓小(這是原生layout viewport變化，
   跟JS的window.innerHeight是否被蓋掉無關)，flexbox預設行為會把#GameDiv連帶往下壓縮，導致遊戲畫面
   看起來只有上下被「壓扁」(不是等比例縮小)。加flex-shrink:0讓#GameDiv維持自己inline style設定的
   高度，改成讓內容被鍵盤蓋住溢出，而不是整個被壓扁變形。 */
/* 2026-09-25：改成只在EditBox編輯中(JS加上.editing-no-shrink)才生效——無條件套用會讓#GameDiv舊高度撐住
   body.scrollHeight，Cocos引擎在Android上把它誤判成虛擬鍵盤，直式拉成橫式時#GameDiv高度卡住(見event.ts) */
