// # t helper
// i18n: Translatable handlebars expressions for templates of the front-end and themes.
// Front-end: .hbs templates in core/server, overridden by copies in themes. Themes: in content/themes.
//
// Usage examples, for example in .hbs theme templates:
// {{t "Get the latest posts delivered right to your inbox"}}
// {{{t "Proudly published with {ghostlink}" ghostlink="<a href=\"https://ghost.org\">Ghost</a>"}}}
//
// To preserve HTML, use {{{t}}}. This helper doesn't use a SafeString object which would prevent escaping,
// because often other helpers need that (t) returns a string to be able to work as subexpression; e.g.:
// {{tags prefix=(t " on ")}}
