/* =============================================================
   journal.css — Journal pages（index + articles）共用樣式
   -------------------------------------------------------------
   設計決策：
     • Tokens 跟主站 style.css 對齊（同色票、同字型 stack）
     • Journal 是「子刊」、視覺要連續、不要看起來像另一個產品
     • article + index 共用大部分元件，少數頁面 specific（cover/toc/specimen）
   MIRROR：主站 style.css 的 :root colors / fonts。改值兩處要同步。
