/* aio.css — AIO対応Webサイト制作ページ固有スタイル
   基盤: basic.css
   参照: services.css の変数・余白・ボーダースタイルに準拠
   ----------------------------------------------------------------
   設計方針:
   - services.css と共通の変数を再定義（このページ単体でも成立するよう）
   - セクションは白背景（aio-section-white）とグレー背景（aio-section-gray）で交互
   - 共通レイアウトは .aio-inner でラップ（sv-main-inner と同幅・同余白）
   - コンポーネント: 比較（aio-compare）/ カード（aio-card）/ フロー（aio-steps）/ FAQ / 表
