Default language and currency: setting the locale of every document

The language setting flows everywhere a string with legal weight is rendered. Email subject lines: "Your proposal from {name}" (EN) becomes "Dein Angebot von {name}" (DE), "Votre devis de {name}" (FR), and so on. PDF section headers ("Service description", "Payment terms", "Total due") translate to match. Statutory disclaimers — VAT exemption notes, reverse-charge wording, late-payment fee references — all switch to the matching locale, with text reviewed by an EU VAT specialist (never machine-translated). The client gets the document in the language you sent it in; if your client asked for German and you sent English by accident, withdraw and re-send.

The currency setting is more constrained than language because not every Stripe account can charge every currency. EUR is universal across the EU; GBP and USD are accepted by every Stripe Connect account in EUR-zone countries; PLN is accepted by Polish-registered Stripe accounts and a few others. If you pick a currency Stripe can't process for your account, Clozo lets you generate the invoice but the "Pay with card" button is greyed out — the client can still pay via SEPA if the IBAN is set. Decimal separator follows your locale: €1,234.56 in EN, 1.234,56 € in DE, 1 234,56 € in FR.
