/* ==================== 页头 tab 栏宽度自适应（项目库 / 跟进库） ====================
   要解决的问题：顶部那一排 tab（项目列表 / 我负责的 / 我关注的 / 标签 / 招商看板 /
   跟踪管理 / 回收站 / 批量管理）+ 右侧操作按钮，在宽屏（Mac）一行放得下，在窄一点的屏
   （Surface）就放不下，被 flex-wrap 挤到第二行，页头忽高忽低、排版来回跳。
   做法：JS（projects.js: fitProjectHeader）量容器可用宽度，放不下就逐级加档位 class，
   档位越深按钮越紧凑；4 档仍放不下才允许按钮等分压缩 + 文字省略——宁可挤一点也不换行。
   ⚠️ gap 一律加 !important：Bootstrap 的 .gap-2 自带 !important，不加压不住。
   ⚠️ 档位名与 projects.js 的 KJ_HD_LEVELS 一一对应，改名字两边要同步。 */
