Multi-language storefront, Castellano + Catalán + Euskera + Galego store views

Spain has 4 co-official languages: Castellano (Spanish, all-Spain), Catalán (Catalonia, Valencia, Balearics), Euskera (Basque Country, Navarre), Galego (Galicia). For serious Iberian merchants this is non-negotiable:

• Catalonia, the Llei de Política Lingüística (1998) requires commerce operating in Catalonia to provide Catalan-language service. Barcelona retailers without Catalan storefronts lose conversion and risk Generalitat scrutiny.
• Basque Country, Euskera is the regional working language for > 30% of the population. Many Basque B2B buyers expect Euskera content.
• Galicia, Galego is universal in everyday commerce.

Magento implementation:

1. One website, four stores, Castellano default + Catalán + Euskera + Galego store views. Shared catalogue, per-store translated product_name / description / meta.
2. Locale-aware URLs, yourbrand.es (default), /ca/ (Catalan), /eu/ (Euskera), /gl/ (Galego). Or subdomain split if you prefer.
3. Hreflang tags, ca-ES, eu-ES, gl-ES, es-ES + x-default. Critical for Google to serve the right language to the right region.
4. Translation workflow, we connect Magento to professional ES→CA / ES→EU / ES→GL translators (Smartling / Phrase / native agencies) for product copy, not machine translation (which fails on Euskera grammar).
