 * ======================================
 * 中田プロパン有限会社 サイト固有CSS（site.css）
 * 追加クラス一覧（共通SCSS取り込み検討用）
 * ======================================
 *
 * 配色・フォントは scss/nakata.scss で共通変数を上書きし css/main.css に反映済み。
 * ここには claude-design-output の見た目を再現するための固有クラスのみを追加する。
 *
 * .nk-header*      - 2段組みスティッキーヘッダー（上部グラデ帯＋ロゴ＋TEL/IG/CTA＋中央ナビ）
 * .nk-logo*        - テキストロゴ（アイコン「中」＋英日社名）ヘッダー/フッター共用
 * .nk-gnav*        - PCグローバルナビ（下線カレント表示）
 * .nk-hero*        - TOP メインビュー（フェード自動スライドショー）
 * .nk-photo*       - 画像＋背後の緑オフセット四角の装飾フレーム
 * .nk-btn / .nk-btn-outline - 緑ソリッド / 緑アウトラインボタン
 * .nk-block / .nk-container / .nk-bg-pale - セクション余白・中央幅・薄緑背景
 * .nk-secthead* / .nk-eyebrow - 中央寄せセクション見出し（英字ラベル＋日本語）
 * .nk-secttl / .nk-subttl - 緑の角丸バー付き見出し
 * .nk-guide* / .nk-promise* - TOP 導線カード / 4項目ナンバーカード
 * .nk-kanta*       - TOP 乾太くん主役バナー
 * .nk-phero*       - 下層ページヒーロー（角丸カット画像＋白ラベル）
 * .nk-panel* / .nk-table / .nk-stack - 白カードパネル / 会社概要テーブル / 縦積み枠
 * .nk-msg* / .nk-feat* - 代表挨拶 / 業務内容の左右交互レイアウト
 * .nk-news* / .nk-kbig* / .nk-talk* / .nk-point* / .nk-bar* / .nk-cost* / .nk-ele* / .nk-info* - お知らせページ各ブロック
 * .nk-notice / .nk-promise-list / .nk-pay* / .nk-sign* - ガス料金ページ各ブロック
 * .nk-help* / .nk-tel-box* / .nk-form* / .nk-field / .nk-privacy* - お問い合わせページ各ブロック
 * .nk-contact*     - フッター直前 CONTACT 帯（画像＋白カード重なり）
 * .nk-footer*      - フッター（会社情報＋サイトマップ＋地図）
 *
 * ======================================
 * 共通SCSSに不足していたもの（5分類）
 * ======================================
 * ・構造不足：2段組みヘッダー、画像＋緑オフセット四角、CONTACT帯の重なりレイアウト、
 *   会話吹き出し、比較バーは共通componentに該当なしのため固有実装。
 * ・装飾パターン不足：下層ヒーローの角丸カット＋白ラベル、緑グラデCTAカード。
 * ・値の粒度不足：見出し英字46〜60px、行間・余白などデザイン固有値。
