/* ===========================================================================
   Miqto 記事共通スタイル + 図解コンポーネント集
   ---------------------------------------------------------------------------
   方針（docs/article-style-guide.md が正本）
   - SVGは一切使わない。図はすべて HTML + CSS（border/gradient/grid）で描く。
   - 外部リソース・Webフォント・画像を読み込まない（表示速度とSEOのため）。
   - 全コンポーネントは 320px 幅で破綻しないこと。表は内部スクロール。
   - 追加するときは必ず「モバイルで縦積みになるか」を先に決めてから書く。
