/* ★2026-10-03(用户 21:26 反馈「小程序后台网页不能自适应屏幕宽度了，画面都看不见了」)：
   今天顶栏又加了一个「📨 客服对话」按钮，`.device-box` 里 select+按钮 的总宽超过了手机屏宽，
   而 `.device-box` 自己不换行 ⇒ 顶栏被撑出屏幕，整页跟着变宽（手机上就被挤得看不清/看不见右边）。
   修：① 基础规则允许换行（桌面不受影响，只有放不下时才折行）；② 窄屏下控制区整行独占，
   按钮自动折到第二行；③ 窄屏按钮/下拉再收小一档。 */

/* ★2026-10-03: 卡片里的长串（版本号/哈希/长 URL/连写的英文）不许把卡片撑宽。
   grid 子项默认 min-width:auto，长串会顶宽整条轨道 ⇒ 手机端整页比屏幕还宽（右边看不见）。
   这条与文件顶部 `.sensor-card-grid` 用 minmax(0,1fr) 是同一类修法。 */
