Which production gettext workflows must work before 1.0?

[yhay81]

The core convention is intentionally small, but the evidence for it should come
from real projects. Before 1.0, which workflows should this repository reproduce
end to end?

Useful reports include:

• your framework and how the active locale is bound per request;
• how messages are extracted and merged;
• which PO editor or hosted translation platform you use;
• how catalogs are checked and compiled in CI;
• lazy translation, plural, or context patterns you depend on;
• deployment constraints such as a Babel-free runtime image;
• performance or concurrency constraints.

Please describe one concrete workflow, what currently works, and the smallest
missing piece. Redacted configuration or a minimal repository is ideal. We will
turn validated, bounded gaps into issues; broad framework-specific layers will
stay outside the project when an example or adapter is enough.
