 着物買取サービス（work-9）— 戦略メモ（Task 1 & 4）
================================================================================
【Task 1 ブランド・情報設計】
1. カラーパレット（16進）
   · 深緑 #2c5f3e — 和の落ち着き・誠実さ・信頼の土台色。安心感を醸成する。
   · 金  #b8963e — 高価値・品格・「大切なものを正当に評価する」姿勢を示す。
   · 墨  #1a1a1a — テキスト。読みやすく、格調のある和のモノクロ。
   · 温白 #f8f5ef — ベース。和紙を思わせる温かみで、高齢層に親しみやすい。
   · 薄金 #e8e0d0 — ボーダー・区切り。温白との差をやさしくつける。
2. サイト構造：Hero（共感と安心）→ 3つの方法（選択肢の提示）→ 出張買取詳細
   → 宅配買取詳細 → LINE査定（最低ハードルで背中を押す）→ 選ばれる理由
   → FAQ（不安解消）→ お問い合わせ → フッター
   「不安 → 理解 → 信頼 → 行動」の心理導線を意識。
3. タイポ：Noto Serif JP（見出し）+ Noto Sans JP（本文）
   和文セリフで格調と信頼感、サンセリフで可読性を両立。

【Task 4 CVR最大化のポイント】
1. FVに「お気軽に」「無料」「損しない」を入れ、心理的ハードルを最小化。
2. LINE査定ボタンを画面下部に固定し、離脱直前でも導線を確保。
3. ステップ図で「わかりやすさ」を示し、「難しい」という思い込みを解消。
4. FAQで査定・キャンセル・梱包など不安ポイントを先回りして回答。
5. Intersection Observer によるフェードインで滞在時間を伸ばしエンゲージメント向上。
