Voice and UI copy

The persona is a senior operator explaining clearly: concrete, calm, no hype.

1. One idea per sentence.
2. Numbers carry a source or are left out.
3. Show the mechanism, not the adjective.
4. Short words over long ones; active voice.

Buttons and errors

• A button is a verb plus an object: “Save changes”, “Enregistrer les modifications”. Never “Submit”.
• An action keeps one name through the whole flow: the button says “Publish”, the toast says “Published”.
• An error says what happened and what to do. It does not apologise and is never vague.
• An empty screen is an invitation to act.

All strings live in messages/{en,fr}.json with the same keys; an Arabic file ships when the zone ships Arabic.
