   墨田スマイル歯科 — KOHO 制作サンプル LP（架空クリニック）
   設計方針：
     - 独立クリニックブランドとして「KOHO 色」を出さず、医療らしい清潔感
     - 主色 deep blue + 補助 warm gold + 温白 background の 3 色のみ
     - Noto Sans JP (palt) + Noto Serif JP（見出しのみ補助的に）
     - 純 HTML/CSS、JS は sticky header の compact 切替のみ
     - prefers-reduced-motion 尊重、a11y セマンティクス遵守
