 * template.css — フォースネット 新テンプレート共通スタイル

 * 抽出元: public/local-ai-box/index.html / public/voice-line/index.html の <style>
 * 目的: company / solutions / contact / news 4 ページが LP と地続きの体験を持てるよう、
 *       ヘッダー / フッター / セクション / グリッド / カード / バッジを共通化する。
 *
 * 命名: LP と同じクラス名（.fn-header / .section / .hero）を維持。
 *       旧 style.css と並列ロードしない前提（新 4 ページは template.css 単体読込）。
