Multi-language DE + EN + TR + AR storefront for Berlin's diverse customers?

Yes, this is a Berlin-specific advantage that the country page can't articulate. Berlin's population is famously diverse: roughly ~200k+ Turkish-heritage residents (Kreuzberg, Neukölln, the largest Turkish community outside Turkey at one point), a substantial Arab-heritage community (Sonnenallee in Neukölln, Wedding), plus an enormous English-speaking startup workforce (Mitte / Kreuzberg). Checkout conversion in Berlin still spikes 15-25% when DE is the default language, but a multi-language Magento storefront with DE-default + EN + TR + AR opens new audience pockets. We wire: (1) separate storefront-views per locale with shared catalogue + per-view price-display rules; (2) right-to-left (RTL) CSS for Arabic via Hyvä / Tailwind dir-rtl utilities; (3) URL slugs translated per locale (e.g. /de/produkte/ + /en/products/ + /tr/urunler/ + /ar/AR-slugs); (4) hreflang tags wired correctly so Google indexes each storefront separately. MwSt 19% applies regardless of customer language.
