/* ===== 手機版導覽列 =====
 *
 * 原本的問題：
 * .nav-links-wrap 是橫向 flex，六個連結沒有設寬度也沒擋收縮，窄螢幕下被壓到
 * 比內容還窄，中文於是逐字直排（375px 實測「課程搜尋」只有 25.1px 寬、105.6px 高）；
 * .header-flex 高度又固定 68px，撐開的選單直接溢出蓋住下方內容。
 *
 * 實測 .nav 高度 vs .header-flex 的 68px：
 *   768px→38.4   600~430px→60.8   398px→83.2   375px→105.6
 * 超過 68px 就開始蓋住下方，也就是 398px 以下會明顯跑版。
 *
 * 做法：不隱藏任何項目（政府網站導覽全可見比藏進漢堡選單好），改成
 *   1. 每個項目給固定寬度 + flex-shrink:0 —— 這是關鍵，項目不再被壓縮，
 *      中文就會在指定的字數換行，而不是逐字直排；
 *   2. 容器 flex-wrap:wrap —— 真的排不下時整列換行，不會再擠成一團；
 *   3. .header-flex 改 height:auto + min-height —— header 跟著內容長高，不再溢出。
 *
 * 寬度用 em：中文字寬剛好是 1em，所以 2em = 每行兩字，4em = 每行四字。
 * 選擇器用 href 屬性而不是 nth-child，日後調整項目順序也不會錯位。
 */

/* 這顆按鈕原本沒有任何樣式卻仍然佔位（被算成 4x4px 的空按鈕）。

     * 用 .header .header-flex（0,2,0）與 .header .container 同權重，
     * 靠 index-inline.css 載入順序在後勝出。 */
    /* 手機版把 header 壓矮：導覽內容本身只有約 43px，
     * 68px 的 min-height 是桌機單行選單的高度，兩行選單用不到；
     * responsive.css 的 15px 上下 padding 在手機上也偏厚。
     * 兩個一起縮，header 從 99px 降到約 64px，而且高度改由內容決定，
     * 窄螢幕導覽換成兩排時會自己長高，不會再溢出。 */
