- Fix vinyl add-on checkout: product line item was dropped when vinyl selected; entryUnitPrice also excluded base product price
- Store vinyl per-letter price on cart entry so CartDrawer charges the config price, not hardcoded 65¢
- Fix two bare modifiers.find() calls (use optional chaining) to prevent checkout crash on bad data
- Validate deliveryCents (must be non-negative integer) and customer name fields (no control chars) in checkout API
- Validate rateOverride values are non-negative numbers in delivery-quote API
- Add RFC 5545 iCalendar escaping to SUMMARY/LOCATION/DESCRIPTION fields to prevent calendar injection
- Add public /api/hours route; pickup and delivery calendars now fetch admin-saved hours and pre-grey closed days
- Reset delivery quote and slot when high-rate item is removed from cart
- Change delivery window copy from 2 hours to 1 hour (DeliveryDatePicker + terms page)
- Fix SVG paths: /color/images/ → /color-picker/images/ (balloon mask, shine, color backgrounds); was causing Safari ? placeholders
- Enlarge padlock icon in PaymentForm from 11px to 14px for better alignment
