Internationalization (i18n)
epresso is single-locale. A site has one language (from site.toml):
toml[site]language = "en"
There is no built-in locale routing, per-language content collections, or
translation dictionaries. If you need a localized site, the practical approach
is one epresso project/site per locale, each with its own site.toml
(language), built and deployed separately.
