Multi-language Swiss site — DE/FR/IT/EN — how should I structure it?

Switzerland has 4 official languages, and Swiss shoppers strongly prefer their regional language. The right Magento structure:

• One website (single product catalog, single inventory).
• One store for Swiss commerce (CHF, MWST 8.1%, Swiss Post rules).
• 4 store views: de_CH, fr_CH, it_CH, en_CH.
• URL structure: /de/, /fr/, /it/, /en/ with hreflang per view (de-CH, fr-CH, it-CH, en-CH).

Translations live in Magento’s native i18n + catalog_product_entity_*_store tables — we manage the translation pipeline (typically via Crowdin or Phrase) so the DE source-of-truth syncs cleanly to FR / IT / EN. Locale-aware schema.org emitted per store-view.
