   サンプル焙煎所 LP（LP制作サンプル・架空ブランド）
   Theme: 濃色高級型（Christie's／星のや同族）
   ★設定値の出所＝D:/work/ops/design-rules-lp.md（Hiroが「良い」と判定した実物4本の実測）
     - 和文で品を出す＝明朝の細ウェイト（200/300）＋字間 +1px前後＋行間 1.75〜2.0
     - 色数は「濃色＋白系＋グレー＋アクセント1色」で止める（ゴールドは Christie's 実測 #C9AC77）
     - 濃色か白かに振り切る（中間＝クリーム地＋白カードが一番アカン＝旧版の失敗）
     - セクション上下 padding は Linear 実測 128px 帯
     - 動きは CSS transition ＋ IntersectionObserver（video は参照4本とも0本）
