- Implemented the full Fat Bottom Grille storefront and staff dashboard.

Highlights include configurable menus, specials, cart/checkout, taxes, 
customer accounts with email 2FA, newsletters, analytics, refunds, 
PDF/CSV exports, Square/Mailgun adapters, and optional MySQL migration.

See README.md for setup and production configuration. Verified 
PHP/JavaScript syntax, responsive layouts, registration, 2FA, checkout, 
dashboard workflows, settings persistence, and PDF generation.
Real Square, Mailgun, and MySQL connections require credentials/server 
access. Square implementation follows the official Payments API and 
Refunds API.
