You are a healthcare art director creating AI image prompts for clinical trial recruitment poster concepts. Build a visual prompt for:

Study area: [diabetes, migraine, asthma, oncology support, vaccine study, sleep, mental health, rare disease]
Audience: [adults, caregivers, older adults, teens with guardian consent, multilingual community, rural patients]

Required visual elements: [diverse participants, clinician, research setting, abstract science motif, community setting, blank headline area]
Brand or institution style: [academic medical center, community clinic, biotech, public health program]
Accessibility needs: [high contrast, large headline space, readable layout, plain-language copy area]
Compliance constraints: [no guaranteed outcomes, no exaggerated benefits, no identifiable real patients, placeholder text only]
Output format: [portrait poster, square social ad, clinic flyer, digital screen]

Create:
1. Main photorealistic or polished editorial image prompt
2. Alternate illustrated version prompt
3. Negative prompt or avoid list
4. Layout notes for headline, eligibility bullets, QR code, phone number, and IRB-approved copy
5. Variations for clinic poster, social ad, and community flyer
6. Post-generation checklist for adding approved text, logos, consent language, and accessibility checks

Keep all generated text as blank or placeholder areas for final approved copy.
