## 1. Executive Summary & Architecture Decisions

All 5 finalized architectural decisions requested by product direction have been incorporated into the planning artifacts:

1. **Architecture Split (DECISION-003 Finalized)**:
   - **Storefront (Customer-facing)**: Next.js framework for server-side rendering (SSR), dynamic open-graph metadata, and maximum SEO performance.
   - **Admin Panel**: Pure, isolated React SPA. SEO is completely irrelevant; absolute priority is **Security**, **Performance**, **Lazy Loading**, and **Type Safety**.
2. **`TASK-FE-001` Refinement (Admin Panel SPA Router)**:
   - Target: Admin Panel React SPA using `react-router-dom` (`createBrowserRouter`) strictly for route-level lazy loading (`lazy()`), chunk splitting, and strict Type Safety. SEO considerations removed.
3. **`TASK-AUTH-001` Refinement (Admin Panel Dual-Token Auth)**:
   - Implements Dual-Token Architecture (In-memory Access Token + HttpOnly Refresh Cookie) specifically for the standalone Admin Panel per [`ADR-AUTH-001`](file:///c:/Users/parsa/Desktop/work/caninairan/docs/audit/ADR-AUTH-001.md).
4. **`TASK-SEC-001` Refinement (Dual Startup Secrets)**:
   - Enforces mandatory bootstrap validation in `main.ts` for TWO secrets: `JWT_ACCESS_SECRET` and `JWT_REFRESH_SECRET` (each >= 32 characters/bytes). Fail fast (`process.exit(1)`) if either secret is missing or insecure.
5. **`TASK-FIN-001` Refinement (`Prisma.Decimal` Payload Serialization)**:
   - Enforces global `DecimalInterceptor` (or DTO `Transform` decorators) converting all `Prisma.Decimal` instances in API response payloads to exact Strings (e.g. `"64.98"`) or precise Numbers before sending to clients, preventing client-side parsing crashes. Corrected total calculation example: `19.99 * 3 + 5.01 = 64.98`.
