Write a UX Copy Microcopy Set

Write a complete microcopy set for this product surface:

Product: [PRODUCT]
Screen / flow: [ONBOARDING, CHECKOUT, EMPTY STATE, SETTINGS, ERROR]
User goal: [GOAL]
Brand voice: [VOICE]
Reading level: [LEVEL]
Primary CTA: [CTA]
Constraints: [CHARACTER LIMITS, LEGAL, ACCESSIBILITY]

Requirements:
1. Cover headings, body helper text, button labels, empty states, errors, success toasts, and confirmation modals relevant to the flow.
2. Prefer verbs and outcomes over marketing fluff.
3. Provide inclusive, accessible wording (no idioms that break localization).
4. Offer A/B variants only where the primary CTA or error recovery benefits from a second option.
5. Flag any copy that needs legal or compliance review.

Deliverables:
1. A labeled microcopy table (element, copy, character count, notes).
2. One alternate CTA set for testing.
3. A short voice checklist the designer can reuse on nearby screens.
