  Kitani Support 修正用コメント付きCSS

  よく修正する場所：
  1. 色を変える        → :root の --green / --blue など
  2. 横幅を変える      → :root の --max
  3. 角丸を変える      → :root の --radius
  4. ヘッダー          → .site-header / .header-inner
  5. トップページ      → .forum-hero / .forum-emphasis
  6. 各ページ上部      → .page-hero
  7. カード類          → .card / .topic-card / .feature
  8. スマホ表示        → @media の中

  注意：
  HTML側の class 名を変更するとCSSが効かなくなるため、
  文章修正だけなら class 名はそのままにしてください。
