   LP テンプレート — main.css スターター
   --------------------------------------------------------------------------
   新案件の Stage 5（フロント実装）開始時に、最低限の可読性・アクセシビリティ
   ルールを最初から組み込んだ状態でスタートできるようにするための雛形。

   このスターターには以下が含まれる：
     - CSS Custom Properties の最小セット（カラー・タイポ・余白）
     - 日本語可読性のためのグローバル設定（自然な折り返し / overflow-wrap）
     - .nowrap / .text-chunk ユーティリティクラス（短い重要語句・文末保護用）
     - .copy-fit / .sp-copy-fit ユーティリティ（長文本文のスマホ見切れ防止）
     - .hero / .section__title / .cta の初期スターター（新規作成直後の崩れ防止）
     - skip-link / :focus-visible のアクセシビリティ最低限
     - prefers-reduced-motion 対応
     - JS 有効時のみ動く .fade-in / .section__title の初期アニメーション

   実装時の注意：
     1. デザイン仕様書 §1〜2 のカラーパレットとフォントを反映
     2. 短い重要フレーズだけ <span class="nowrap"> で保護
     3. 本文は句点・意味単位で <br> や短い段落に分ける
     4. 長い本文・商品名列挙・注記は .copy-fit または .sp-copy-fit で見切れを防ぐ
     5. body に word-break: keep-all を強くかけない。必要な箇所だけ局所保護する
