/* ============================================================
   DemoShop MEMBERS — 別デザイン版（マニュアル／MNCT系の世界観）
   syncflows-manual と同じデザイン言語を会員アプリUIへ移植：
   ・モノクロ（墨・ペーパー・muted・罫線）／差し色の背景ボックスは使わない
   ・和文ゴシック（Hiragino Kaku Gothic系）／セリフは使わない
   ・角は立てる（border-radius 0）／影は使わない／細罫線と余白のリズムで区切る
   ・見出し・価格は太字＋広めのレタースペーシング、タブラー数字
   ※クラス名は本番CSS(style.css)と共通。dist-monoでは本ファイルをstyle.cssとして配信する。
