Shoppers can register, save shipping details, and view order history while cards stay on Stripe. EasyPost tracker updates (including numbers from Pirate Ship) and 1–5 star reviews are limited to buyers. The contact form now only asks for email and a message.
## Summary
- Rebrand the Django client template as Print Forge (`client_site` → `print_forge`) with shop + shipping enabled.
- Product listings support multiple photos, color variants (shared price/description/STL, per-color stock and photos), and a photo-first / 3D-second gallery.
- Public pages use 3D printer / printed-toy photography instead of leftover t-shirt mockups; beta CI deploys on `master`.
Closes#1
Infra: [server-infra#27](ai_ml_operations/server-infra#27) (easy deploy beta).
