+alwaysApply: true

+
+Shared package and dependency standards for the monorepo.
+
+## Package management
+- Use `pnpm` workspaces.
+- Prefer workspace packages for shared logic rather than duplication between apps.
+- Reusable logic should be extracted into `packages/*` only when there is a clear second use case or a foundational shared concern.
+
+## Dependency rules
+- Prefer fewer dependencies.
+- Do not introduce a package solely for convenience if existing platform APIs or current project dependencies can solve the problem cleanly.
+- Any new dependency must be justified briefly in code comments, PR notes, or task summary when it is not obvious.
+- Use the latest stable non-beta version when adding dependencies.
+- Prefer mature, actively maintained packages with strong TypeScript support.
+
+## Shared package direction
+Prefer dedicated packages for:
+- UI primitives
+- shared types
+- shared schemas
+- configuration
+- internationalization helpers
+- eslint config
+- tsconfig
+- test utilities when broadly reused
