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.
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.
