crstnrjs/PintaPatitas ? reverse-engineered prompt

Build me a full web app for PintaPatitas, a Chile based store that sells custom pet portraits.

I want a polished public landing page with a dynamic catalog, product details, and a step by step order form where customers can choose the technique, size, number of pets, upload photos, and enter delivery information. The flow should feel simple and friendly on mobile and desktop.

Also include a private admin area at /admin where I can review requests, see basic metrics, track order status, and manage the catalog. The backend should handle pricing automatically, validate uploaded files, store pet photos securely, and send confirmation emails when orders are created or paid. If you need to check current docs for any library or service, feel free to look them up online.

Keep the design clean, cute, and modern, with a strong focus on making the ordering process feel trustworthy and easy.
