フォーカスインジケーターを敢えて :focus で実装する
WCAG の達成基準を満たすのであればフォーカスインジケーターは CSS の :focus-visible 擬似クラスによる実装で十分ですが、より多様なユーザー体験を考慮に入れると、:focus 擬似クラスによる実装がベストと言えます。WCAG を超えたユーザー体験 (Beyond WCAG) を目指すなら、こうした実装も意義のあるデザイン判断になるかと思います。

Stop Misrecruits: Add Foils to Your Screener

Liquid Glass Is Cracked, and Usability Suffers in iOS 26
iOS 26’s visual language obscures content instead of letting it take the spotlight. New (but not always better) design patterns replace established conventions.
