/**
 * Time Value Architect — time-value-architect.css
 *
 * 設計思想:
 *   - #tva-root 配下のみ完全独立デザイン
 *   - Cocoon / entry-content / article 干渉を完全排除
 *   - CSS カスタムプロパティで全色・全値を管理
 *   - モバイルファースト + clamp() 流体タイポグラフィ
 *   - アニメーションは opacity / transform / filter のみ使用
 *   - カラーパレット: 深黒オブシディアン × 焦がしゴールド × アイボリー × 紫黒アクセント
 *   - フォント: Cormorant Garamond (欧文Display) + Shippori Mincho (日本語明朝) + Noto Sans JP
