/* ============================================
   はてなブログ カスタムCSS（高さ調整版）
   ============================================
   堅牢デザイン版をベースに高さ・縦余白を調整（デスクトップ・モバイル両方）
   行間・見出し前後の余白・タップ領域・セクション間の空きを統一して見やすく
   ============================================
   動画クリエイター向け・堅牢感のあるトーンに統一
   フォント: ゴシック体（システムフォント）で読みやすく / カラー: 濃いめテキスト・はっきりしたアクセント・境界線
   CLS対策は継承（body余白・広告枠・font-display 等）
   ============================================
   モバイルCLS対策を反映:
   - フォント optional / body・#blog-title でヘッダー高さを事前確保
   - #ins-ads-toc に min-height・aspect-ratio / 読者になる .header-subscribe に min-height
   - サイドバー広告・目次上広告枠に min-height / 読者になる枠に min-height
   ※ テーマで body に padding-top を指定している場合は重複するため、当該ルールを削除するかテーマ側を調整してください。
   ============================================
   構成:
   1. システム・基本設定・フォント
   2. 本文・見出し・目次・リンク
   3. カテゴリ・タグ（記事・サイドバー）
   4. コード・テーブル・装飾
   5. ヘッダー（固定・ナビ・検索・読者になる）
   6. フッター
   7. レスポンシブ・サイドバー並び替え
   8. 広告・画像・記事リスト・パンくず・日付
   9. 記事ヘッダー・モバイル記事ページ
   10. プロフィール・ポップアップ・シェア
   11. その他（横揺れ防止・ツイート風・ボタン等）
   ※ ブレークポイント: 767px（モバイル）/ 768px（一部）/ 480px（小型スマホ）
