① Safari <15 不支持 aspect-ratio：回退 padding 撑高，防止卡片塌成零高度；
② 这一代 WebKit 还有"圆角容器内的子元素进入合成层（transform/opacity 动画）后圆角裁剪失效"
的已知 bug：悬停缩放 .case-bg 时四个圆角会被方角图片盖住（用户 2026-09 在苹果电脑上反馈）。
.case-clip 的 -webkit-mask-image 只是通行兜底、并非 100% 保险，所以这里再彻底取消一切
"会改变尺寸/位置并触发合成层"的效果，只保留不改变尺寸的悬停反馈：
· 图片不再缩放，改为轻微平移（background-position）
· 覆盖层文字与"查看详情"只做透明度渐显（去掉 translateY）
这样任何全尺寸元素都不会越出卡片，圆角在任何情况下都不会被破坏。

两者优先级相同，同优先级时后写生效，否则兜底会被覆盖（旧 Safari 认得 transform）。 */
