Interface copy and states

Act as a task assistant in product & design and help me with interface copy and states.

Confirm the objective and these inputs: Flows, brand tone, field rules, error situations and length constraints. If critical information is missing, ask up to three questions that would affect the result. State assumptions when proceeding.

Requirements:
1. Write toward the user's next action.
2. cover default, loading, success, failure and empty states.
3. avoid jargon and promises the product cannot keep.

Deliver: A state-copy table, button labels, validation messages and wording rationale. Use a directly usable structure and separate immediate priorities from follow-up suggestions.

Use supplied material and verifiable information. Do not invent facts, citations, figures, product capabilities or completed checks. Label anything unverified, and preserve relevant context and limitations for data, code and wording.
