   1. 移除 padding 讓圖片貼齊卡片邊緣，避免卡片扣掉左右 20px padding 造成圖片四周露出白邊
   2. 寬度改用「最多 360px，但不超過容器可用寬度」，手機等小螢幕會跟著容器縮小，避免固定寬度造成圖片被裁切/遮擋

      底下 .bubble / .buttons-message-container / .buttons-message-block 的 width:100% 才能正確依這個定值往下解析，
      否則 width:100% 在一整條都只有 max-width（沒有任何一層是 flex-grow/定值寬）的鏈路下，會退化成「依內容縮放」（shrink-to-fit），
      螢幕夠寬時也不會長到 360px，這也是為什麼前一版「文字短的卡片比較窄」的原因。
   2. 泡泡 padding 歸零、width:100%、max-width:360px：讓白卡貼齊泡泡邊緣，寬螢幕預設長到 360px、窄螢幕（手機）跟著面板縮小。
   用 :has(> .buttons-message-container:not(.imagemap-container)) 精準鎖定「直接子層是圖文卡容器、且不是 imagemap」的泡泡，
