Code Review
This pull request adds focus-visible styles to the header links and buttons to improve keyboard navigation. The reviewer recommends replacing the Tailwind ring and ring-offset utilities with native outline and outline-offset styles. This adjustment ensures compatibility with Tailwind CSS v4 and improves accessibility, particularly for Windows High Contrast Mode.

Tailwind CSS v4（globals.css で @import "tailwindcss"; が使用されているため）では、従来の ring-offset-* ユーティリティ（ring-offset-2 や ring-offset-gray-950 など）は非推奨または削除されています。
また、box-shadow を使用する ring は、Windows の高コントラストモード（Forced Colors Mode）でフォーカスリングが表示されないというアクセシビリティ上の課題があります。
代わりに、ブラウザのネイティブな outline と outline-offset を使用することをお勧めします。これにより、Tailwind v4 との互換性が保たれ、コードもシンプルになり、アクセシビリティも向上します。

rounded クラスが付いていないため、フォーカスリングが矩形になります。ナビリンクやボタンはすべて rounded-full で丸形リングが表示されるため、視覚的な統一感が損なわれます。rounded-md を追加することで他の要素と近いスタイルになります。

ロゴリンク（「OpenShelf」）にのみ `rounded` クラスが付いていないため、フォーカスリングが矩形になります。ナビリンクやボタンはすべて `rounded-full` で丸形リングが表示されるため、視覚的な統一感が損なわれます。`rounded-md` を追加することで他の要素と近いスタイルになります。

Closing because this Jules-managed branch cannot maintain a stable review-loop head: after the target branch is incorporated or a review fix is pushed, the bot appends the original generated change again. The current head is therefore not reliably the commit that passed target-fresh CI and review. |

💡 What
ヘッダー内のナビゲーションリンク、ロゴ、ログイン・ログアウトボタンに、キーボードフォーカス時（Tabキー操作時）に表示される視覚的なフォーカスリング（
focus-visibleスタイル）を追加しました。🎯 Why
キーボードユーザーが現在どの要素を操作しているのかを明確にし、サイト内のナビゲーションをより簡単かつ確実に直感的に行えるようにするためです。
📸 Before/After
focus-visible時にはっきりと見える2pxのリングとオフセットが表示され、ダークモードにも対応した明確なフォーカスインジケータが表示されます。♿ Accessibility

Greptile Summary
ヘッダー内の4つのインタラクティブ要素（ロゴリンク、ナビリンク、ログアウト・ログインボタン）に
focus-visibleスタイルを追加し、WCAG 2.4.7 (Focus Visible) に準拠したキーボードアクセシビリティを向上させた変更です。ライトモード・ダークモード両対応のfocus-visible:ring-2+ring-offset-2スタイルが一貫して適用されています。focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-gray-900 focus-visible:ring-offset-2を追加。dark:focus-visible:ring-gray-100 dark:focus-visible:ring-offset-gray-950でコントラストを確保。roundedクラスが未設定のため、フォーカスリングが矩形になる点が他要素と不統一。Confidence Score: 4/5
スタイルのみの変更でロジックへの影響なし。ロゴリンクの角丸スタイル欠落が見た目の不統一を生むが、機能上の問題はない。
変更はすべて Tailwind CSS クラスの追加のみで、コンポーネントのロジックや動作には一切影響しない。ロゴリンクに
roundedクラスがなくフォーカスリングが矩形になるため、他要素（rounded-full）との視覚的一貫性が欠けているが、これは機能的な欠陥ではなくスタイルの改善余地。apps/web/src/components/header.tsxのロゴリンク部分にrounded-mdを追加するとスタイルが統一される。Important Files Changed
focus-visibleスタイルを追加。ロゴリンクのみroundedクラスがなく、フォーカスリングが矩形になる点が他要素と若干不統一。Flowchart
