# UI + Checkout Update

Updated 2026-08-30.

## Changes
- Fixed `Undefined variable $invoiceNumber` in `CheckoutController` by passing the service into the transaction closure.
- Removed the floating left-side Call / WhatsApp / Instagram / Facebook social button stack.
- Removed `Categories` from the customer navigation bar.
- Changed Shop category filter pills from horizontal scrolling to wrapping onto additional lines.
- Moved the public `Product List PDF` action into the Shop header toolbar beside the search area.
- Kept compact Shop product rows and existing +/- cart controls.
- Preserved the common Home/Shop hero and existing footer social links.

## Validation
- `php -l app/Http/Controllers/CheckoutController.php` passes.
- `php artisan route:list --path=shop` confirms the Shop route.
