🧹 Refactor: Remove redundant useEffect and set-state-in-effect override in useCardSettings

[is0692vs]

🎯 What: Removed the isHydrated local state and the redundant state-initialization useEffect in the useCardSettings hook.
💡 Why: The initial state for layout and displayOptions is already correctly provided by their respective lazy useState initializers via loadCardSettings(). Running a subsequent useEffect merely to verify and duplicate this same loaded state caused unnecessary renders and triggered an eslint-disable rule evasion. Removing it makes the logic cleaner, faster, and resolves the linting violation.
✅ Verification: Verified by ensuring the layout renders properly and all unit tests in the suite (including npm run test across 599 assertions) successfully passed. npm run lint also confirmed the react-hooks/set-state-in-effect warning was eliminated.
✨ Result: Improved maintainability, slightly improved performance by avoiding a superfluous render cycle, and a clean codebase free of evasive eslint-disable comments in this hook.

Greptile Summary

この PR は useCardSettings から hydration 用 state と再読込 effect を削除し、設定の永続化条件を mounted のみに簡略化します。

• レイアウトと表示オプションの初期化を lazy initializer のみに変更
• isHydrated による localStorage 保存ガードを削除
• SSR で得たデフォルト値が保存済み設定を上書きする回帰が残っています

Confidence Score: 4/5

保存済みのカード設定をデフォルト値で上書きするため、この回帰を修正してからマージする必要があります。

useCardSettings はサーバーレンダリング時にデフォルト設定で初期化されますが、クライアントで mounted が true になった際に localStorage を復元せず、そのデフォルト設定を直ちに保存します。

### Issue 1
src/hooks/useCardSettings.ts:19-25
**SSR初期値が保存設定を上書き**

保存済み設定がある状態で `CardGeneratorModal` がサーバーレンダリングされると、`loadCardSettings()` は `window` がないためデフォルト値を state に保持します。クライアントで `mounted` が true になった際、この effect は `localStorage` を再読込せずデフォルト値を保存するため、ユーザーのレイアウトと表示オプションが失われます。

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Refactor useCardSettings: remove redundant hydration effect

✨ Enhancement 🕐 Less than 10 minutes

AI Description

• Remove hydration state and mount-time state-reset effect from useCardSettings.
• Rely on lazy loadCardSettings initializers for layout/options without duplicate renders.
• Simplify persistence effect guard/deps and eliminate set-state-in-effect lint suppression.

High-Level Assessment

The following are alternative approaches to this PR:

1. Single initialization read (load once)

• ➕ Avoids calling loadCardSettings() twice during initial state setup.
• ➕ Ensures layout/options are always loaded from the same snapshot.
• ➖ Requires minor refactor (store initial object, then split into two states or keep combined state).
• ➖ May slightly complicate typing/updates if layout/options are updated independently.

2. Persist via wrapped setters instead of an effect

• ➕ Eliminates a useEffect-driven persistence path and dependency management.
• ➕ Can reduce redundant writes by persisting only on explicit user actions.
• ➖ More invasive API change (callers must use provided setters).
• ➖ Harder to guarantee persistence on all state transitions without discipline/tests.

Recommendation: The PR’s approach is appropriate: the lazy useState initializers already load settings correctly, so the mount-time “rehydration” effect was redundant and triggered extra renders plus lint suppressions. Consider a follow-up to load settings once (instead of two separate loadCardSettings() calls) to reduce duplicated LocalStorage reads and keep layout/options in sync from a single snapshot.

Remove hydration state and redundant mount re-initialization effect

• Deletes the isHydrated flag and the mount-time effect that reloaded settings and conditionally set state. Simplifies the persistence effect to run when mounted and settings change, removing lint suppressions and reducing an unnecessary render cycle.
