 * ================================================================
 *  - 顏色：用 #RRGGBB 色碼，可到 https://htmlcolorcodes.com 挑色
 *  - 尺寸：數字後面要保留單位 px
 *  - 改完存檔、重新上傳 Netlify 即生效
 *
 *  另外，管理員也可以在後台 admin.html 的「外觀設定」直接用色票調整，
 *  不用改程式碼。後台存的設定會「蓋過」這裡的預設值；
 *  在後台按「還原預設值」並儲存，就會回到這裡寫的值。
 *
 *  品牌色取自官方 Logo 檔案：主色 #01A493、Logo 圖標黃 #FACD00
