//! Integration tests for the Phase E framework-bundle pipeline.
//!
//! Verifies:
//! - `I18nConfig::framework_locales(teksilo_widgets::framework_locales())`
//!   registers the widget bundle at manager construction time.
//! - `tr_widget!` inside teksilo-widgets resolves through that bundle at
//!   runtime (not only via the compile-time static fallback).
//! - The default path — no explicit registration — still yields the
//!   correct English text via the macro's compile-time fallback, which
//!   is what the unit tests rely on.
