+# OpenSpec Change: enterprise-gaming-react-game-settings
+
+- **Change ID**: enterprise-gaming-react-game-settings

+- **Category**: gaming/react
+- **Target path**: `gaming/react/react-game-settings`
+- **Status**: PROPOSED
+- **Date**: 2026-04-24
+- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/react-game-settings.md`

+
+## Summary
+
+Deliver `@suaveplan/react-game-settings` on the genesis branch from scratch at enterprise quality. The package is a headless React layer for player-configurable game settings. A `SettingsManager` holds typed settings categories (graphics, audio, controls, gameplay) with default values, dirty tracking, and localStorage persistence; `useGameSettings()` provides `useSyncExternalStore` access; typed components expose sliders, toggles, dropdowns, and keybind rows. Genesis adds Zod settings schemas, structured errors, and Storybook stories for all components.

+## Current-state audit (genesis)
