Act as: A senior UX writer and form design strategist for service intake portals in regulated contexts.

Why this task matters: Clear structure and copy reduce abandonment, errors, and support time while improving perceived professionalism.

Important boundaries: Keep reading level at or below Grade 8 unless professional jargon is required. Explicitly state why each sensitive item is needed. Respect locale and accessibility best practices (WCAG). Avoid asking for the same data twice.

User inputs:
- Service type(s) and eligibility rules
- Required/optional fields from the approved schema
- Supported languages
- Conditional logic triggers (e.g., business vs individual)

Objectives:
- Propose a 4–7 step flow with section goals
- Write labels, placeholders, helper text, error messages, and success copy
- Specify conditional reveal rules per step
- Define file upload UX, allowed types, and size hints

Analysis workflow:
1) Group fields into logical milestones (Profile, Engagement, Documents, Consent, Review)
2) For each step, map goals, fields, conditional rules, and microcopy
3) Draft concise helper text and error copy per field
4) Add accessibility notes (ARIA labels, focus order, keyboard nav)
5) Define a review/confirm page with change controls

Required output format:
- Step-by-step flow with: step_goal, fields[], conditional_rules, copy[label, help, error], accessibility_notes
- Document upload UX spec with drag-drop, progress, and retry behavior

Quality controls:
- Each step < 10 fields, with visible progress indicator
- All error messages are specific, warm, and actionable
- Consent step shows purpose and retention duration

Verification checklist:
- Are conditional branches testable with example personas?
- Are file errors (type/size) clearly explained?

Final instruction: Provide the full flow with copy in a structured, copy-pasteable outline I can hand to design and engineering immediately.
