+# ENHANCMENTS
+
+## Pull Request Summary
+
+Modernized the app foundation and completed the migration work across TypeScript, Redux, Prisma, and project structure.
+
+## Changes Made
+
+- Migrated the app into the `/src` directory structure.
+- Updated the project to Next.js 16.
+- Migrated JavaScript files to TypeScript/TSX.
+- Updated `tsconfig.json` for current TypeScript behavior by removing deprecated `baseUrl`.
+- Added strongly typed Redux store exports:
+  - `AppStore`
+  - `RootState`
+  - `AppDispatch`
+- Added typed Redux hooks:
+  - `useAppSelector`
+  - `useAppDispatch`
+- Strongly typed Redux slices:
+  - cart
+  - product
+  - address
+  - rating
+- Typed Redux reducer payloads using `PayloadAction`.
+- Updated Redux consumers to use typed hooks instead of untyped `useSelector` / `useDispatch`.
+- Fixed Redux-dependent TypeScript issues in cart, product, order summary, navbar, and product components.
+- Upgraded Prisma schema for Prisma 7 compatibility.
+- Removed deprecated Prisma `driverAdapters` preview feature.
+- Removed deprecated `url` and `directUrl` datasource fields from `schema.prisma`.
+- Added `prisma.config.ts` for datasource configuration.
+- Updated Prisma generator to use `prisma-client` with explicit output path.
+- Added generated Prisma client output to `.gitignore`.
+- Resolved TypeScript issues around:
+  - file upload state typing
+  - dashboard revenue number typing
+  - invalid JSX props
+  - coupon object typing
+  - textarea `rows` value typing
+- Addressed package vulnerabilities through dependency updates.
+- Prepared project for Prisma PostgreSQL adapter setup.
+
+## Verification
+
+- Ran TypeScript validation:
+
+```bash
+npx tsc --noEmit --pretty false
+```
+
+- TypeScript now passes successfully.
+- Redux selector type errors are resolved.
+- Prisma schema no longer uses deprecated datasource URL fields or deprecated preview feature config.
