/* 業務基本流程 — 蛇行（S 形）動線，12 張卡片以箭頭串接
   2026-08：原為 flow-chart.jpg，改為純 HTML/CSS。
   ・用 CSS Grid 顯式 grid-area 定位（非 float），偶數列反向排，形成 S 形。
   ・::before = 連接線、::after = 箭頭，兩者都只走在 grid 間隙裡，不會壓到卡片內容。
   ・每個節點最多一個連接器：列中間→水平、列尾→向下、最後一個→無。
   ・箭頭的 border-color 一律寫四值簡寫：方向會隨斷點改變，只設單邊會殘留前一個
     斷點的顏色，導致箭頭變成方塊。
   ！步驟數改變時三個斷點都要重算 —— 產生器見 scratchpad/gen_flow_css.py */
