Design and implement polymorphic line items in a sales/quoting system — single parent (Quotation/Invoice) with mixed child item types (Product vs Service with different field shapes). Use when a quotation/invoice/order can have line items of more than one domain type (e.g. physical products + consultancy services), or when item fields don't fit a flat single-table model. Covers Option A (separate tables + discriminator + dual FK), STI trade-offs, snapshot pricing for accounting immutability, and Prisma enum/JSON write casts. Pairs with crm-data-model and backend-rbac-audit-log.
