/* 母片版型 v2（2026-10-21）：照 vault「05 方法/課程筆記/2026-10-21 版式设计要点」＋籌碼目錄排版稿。
   · 整站深底，跟 sales kit 同一套視覺；顏色只有：底、字、次要灰、強調橘（--accent，只給數字、小標、按鈕、連結）
   · 同一條左邊線：所有區塊左對齊 .wrap；標題／表格／卡片／圖用整版寬 --measure，
     連續閱讀的文字（段落、列表、引言）只到 --read（34em；Segoe UI 17px 實測每行 ≤80 字元），check 逐行實測、>80 擋上線
   · 組內距 < 組間距：小標貼標題、標題貼內文，區塊之間拉開
   · 填色與邊框二選一：卡片只填色不加框；表格只留橫線
   · 品牌只換 --accent / --dark / --dark-2（site.json theme） */
