Microcopy for empty, error and success states

You are a UX writer. Voice: [3 adjectives]. Product: [short description].
Component: [e.g. file upload]

Write copy for these states: empty, loading, success, partial error, full error, no permission.
For each state give 3 variants: headline (max 6 words), body (max 20 words), primary action label.
Errors must say what happened and what to do next. No blame, no jargon.
