   MACHI CREATE ポータル「AIでつくる街」 2026-09
   ・第2弾：デジタル・シャープ。角丸は使わない。細い罫線・方眼
   ・第3弾：「厚みのある板」の立体感（上面＝明るい／正面／右の側面＝暗い、奥行きは右上45度）。
           3Dの街（面の向きの3段階の濃淡）と同じ光の向きで、カード・ボタン・パネルも板にする
   ・ヒーロー = 地平線まで広がる3Dの街（assets/js/portal-town-2026.js が描く）
   ・「横長レイアウト」の条件は portal-town-2026.js の LAYOUTS と必ず揃えること
       (min-width:900px) and (min-aspect-ratio:11/10), (min-width:640px) and (min-aspect-ratio:3/2)

   第6弾：少しの透過（すりガラス）で、シンプルに・要素の主張を抑える
   ・板の上面・側面も半透明に（厚みはそのまま、存在感だけ軽く）
   ・MVの表示類（状況表示・情報パネル・建物リスト・ボタン）は明るいすりガラス、夜は暗いすりガラス
   ・ページのカードは半透明の白＋細い光の縁。背景にごく淡い色のにじみ（ガラス越しにほんのり見える）
   ここから下を消せば第5弾の見た目に戻る
