# Proposal: catalog-i18n-currency

## Why
Merchants must manage products (create, edit, publish/unpublish) and shoppers must browse a localized, multi-currency storefront. This phase delivers the catalog core plus the currency infrastructure every price display depends on.

## What changes
- Schema: categories, products (JSONB i18n name/description), skus (price minor units + currency + stock), currencies (rate_to_base).
- Public APIs: product list (paged, filter by category/q/shop), product detail by id/slug, category list, currency list + conversion endpoint.
- Shop-admin APIs: product CRUD, SKU upsert, publish/unpublish transitions.
- Seed: base currency USD, plus CNY/EUR/JPY; demo categories.

## Non-goals
- Inventory reservations/warehouses, product variants matrix UI, image upload (URLs only).
- Full-text search engines; ILIKE search is sufficient for MVP.

## Capabilities
- `catalog`: categories, products, SKUs, publish lifecycle.
- `currency`: currency registry and conversion.
