Personalization, gift box, message card, monogram embossing. How does Magento handle it?

Three layers, all wired on the same Magento PDP / checkout:

• Gift box style (configurable product variant: heart / square / ribbon-tied / kraft / corporate-branded). Each style is an attribute option with its own image swatch. Hyvä renders the picker above the cart button.
• Message card (custom product option, text field, max-character live counter, profanity filter). Live preview rendered with the customer’s text on the card image, built with Alpine.js + a font-rendered SVG overlay. Adds ~$0 cost, ~30% conversion lift on gift orders.
• Monogram embossing (additional SKU, 2-day production add to lead time). Live preview of the monogram on the chocolate / box rendered the same way. Charges $5, $15. Margin-positive after one order.

At checkout, multi-address ship-to per line item (native Magento) lets the customer send 5 different boxes to 5 different recipient addresses in one order. Critical for corporate gifting (HR ships 200 boxes to 200 employees) and also for “send my mom + my mother-in-law + my grandma” gifting peaks.

Sugarfina ships this exact pattern. Truffle Truffle has been on this Magento setup since 2018. Shopify Plus needs a $200, $400/mo combo of apps (Gift Reggie + Wrapin + Multi-Address Checkout) to approximate it, and the live-preview UX is consistently worse.
