// Typed message functions for the app. `m.landing_title()` returns a branded
|
|
// I18nString, so it satisfies the @pikku/mantine i18n gate exactly where the old
|
|
// `t('landing.title')` used to — no call-site boilerplate.

|
|
// Each message is wrapped once so i18n-debug masking (█) still works (parity with
|
|
// the old i18next postProcessor). Wrapping the whole namespace forgoes Paraglide
|
|
// per-message tree-shaking — fine here: locale files are KB and the app bundled
|
|
// all of en.json under i18next anyway.
