   バディエステート 福岡支店 中央区今川 — 特設ページ
   Design: 「雪明り／yuki-akari」— 旧唐津街道の宿場町に、
   夜灯りが雪を照らす福岡の冬景色
   ------------------------------------------------------------
   Signature element: スクロール連動の「六花（ろっか／雪結晶）」
   インジケーター（.progress-rail / #progressLeaf）。
   script_branch_detail.js は要素の top(%) と rotate(deg) を
   スクロール量に応じて書き換えるだけなので、windmill から
   六角の雪結晶に差し替えるだけで「読み進むほど結晶が舞い降りる」
   体験になる ＝ JS不変・見た目とレイアウトは全面刷新。
