 ### Tier 5 — Platform vision

 17. **Migration & export** — Let shop owners export their data (products, orders, customers, theme settings). Import from other platforms (Shopify, WooCommerce). Portable data as a selling point for the self-hosted story.
 18. **Internationalisation (i18n)** — Multi-language support via Gettext (already in Phoenix). Currency formatting. RTL layout support. Per-shop locale configuration. **Note:** `ex_money`/`ex_cldr` are currently used *only* for `Cart.format_price/1` (a single GBP formatting call) but add ~13 MB to the release (ex_cldr 9.5 MB, digital_token 3.7 MB, ex_cldr_numbers, ex_cldr_currencies). Consider replacing with a simple `format_price/2` function that handles GBP/EUR/USD directly — all three use 2 decimal places and are trivial to format. Re-add `ex_money` later if proper locale-aware number formatting is needed (e.g., German `12.345,67 €`).
