   buyer_roykirkham_blenheim_event ─ Pattern 04 コレクター限定型
   ロイカーカム ブレナム宮殿コレクション ─ バイヤーイチオシ vol.86
   base : tmp/pattern_04_preview/preview.html (2026-05-13 sample)
   C案版 (2026-05-15 採用4点・歴史紹介3章 / 10 wrapper構成)
   palette : ヴィンテージ／英国カントリーハウス系
     #f6e6c2 (light_bg) / #3a2f1f (vintage_bg)
     #2a2317 (ink_dark) / #c8a45e (gold accent)
   notes:
     - Pattern 04 リファレンス実装（C案版 = 在庫切れ100%対応・歴史紹介パターンB混在）
     - .wrapper_top, _first, _second, _third, _fourth, _fifth, _sixth,
       _seventh, _eighth, _footer の10つにスコープ限定（A-42 グローバルタグセレクタ禁止）
     - font-size は px 直書き（pattern_baseline_fonts § 4-B）
     - lenoble既存クラス（.contents_button / .seriesBtn 等）非依存・preview.html由来クラスで完結
     - 偶数 wrapper（top/second/fourth/sixth/footer）= ヴィンテージセピア背景
     - 奇数 wrapper（first/third/fifth/eighth）= 薄ベージュ背景
     - wrapper_seventh は buyer_voice（vintage_bg） / wrapper_eighth は FAQ（light_bg）
     - FAQ は HTML 2カラム化（.faq-column×2）+ Grid 1fr 1fr（mens_pair_time 教訓）
     - 歴史紹介 figure は実画像比率: buyer86_06(1400/618) / buyer86_10(1400/399) / buyer86_12(1400/524)
     - Collection 01 は マグ3色集合（.collection-grid--3col 新規）
     - Collection 02 は単品大判（.collection-figure--large）
