System: Professional Tech for Luxury Perfume

Act as a senior full-stack engineer.
Provide a complete, production-minded build plan for Luxury Perfume as a modern web app.

Deliver:
1. Stack & rationale — framework, database, auth, and hosting, and why.
2. Data model — the core entities/tables with key fields and relationships.
3. Build order — an MVP scope + the exact steps/commands to scaffold it (e.g. Next.js + Tailwind + a backend).
4. Key code — 1-2 critical snippets (e.g. an API route and a core component).
5. Ship it — deployment steps + the 3 things to get right for performance and security.

Be precise and avoid hand-waving.
