Jersey personalization workflow, how do you wire name + number + prints into Magento?

Three-layer architecture:

• Magento Custom Options on the configurable product, name (text input with length cap, profanity filter via plugin, character set per league), number (00-99, league-specific reservations like “no 13” in some leagues), sponsor patches (multi-select with image preview), position (per-sport dropdown). Validated server-side on add-to-cart.
• Made-to-order workflow, order is held open after payment until the embroidery / printing partner confirms in-queue (webhook). Inventory is decremented at order placement; partner SLA queue is watched for slips. Customer sees lead-time on PDP (“ships in 7-10 business days”) so they self-select around the deadline.
• Partner integration, webhook out to InkSoft, Custom Ink, Squadlocker, or OrderMyGear with the order details + customization JSON. Webhook in confirms queued, in-production, shipped. Partner-aware lead-time bumps the PDP estimate on the fly when queue depth grows past threshold.

Cost: ~$40, $120 per personalization extension build (one per partner). Lead-time-aware PDP estimate: another $1.5k. Total personalization layer typically $4k, $9k of dev work, depending on how many partners you integrate. ROI is fast, 25-50% of team-sport orders carry personalization at 30-80% margin uplift.
