/* =========================================================
   KV Article Components v2.0（2026-08-18）
   ---------------------------------------------------------
   目的：讓長文的閱讀節奏活潑起來。v1（style.css）已有
   導讀框 / FAQ 手風琴 / Prompt 框 / 文末 CTA；v2 補上
   「卡片化、標籤化、對照化」這一層，並強化既有元素
   （h2 / h3 / 清單 / 表格 / 圖說 / 引言 / 分隔線）。

   規範
     ‧ 色彩只用 v1 已定義的品牌變數與其 color-mix 衍生，
       不新增任何品牌色（--kv-ink / purple / lilac / aqua
       / text / line / grad）
     ‧ 全部 scope 在 .single-post .entry-content 底下
     ‧ 只在 is_singular('post') 載入（見 functions.php）
     ‧ 依賴 blocksy-child-style，確保排在 style.css 之後，
       同權重規則才蓋得過 v1
     ‧ 斷點沿用 Blocksy 內建：999.98px、689.98px
     ‧ 對比原則：膠囊標籤一律「深底白字」或「淺底深字」，
       不用紫底白字（#ae6cdc 對白只有 2.6:1）
