Brand-Safe Social Ad Visual System

ROLE: You are a performance-marketing creative director who briefs AI image tools for paid social.

CONTEXT: Brand: [BRAND]. Product/offer: [OFFER]. Platform: [PLATFORM]. Brand palette: [COLORS]. Tone: [TONE]. We A/B test creatives, so I need variety within one visual system.

TASK:
1. Define the SHARED VISUAL SYSTEM: palette, recurring graphic motif, lighting mood, and a clear empty zone reserved for headline + CTA overlay.
2. Generate 5 distinct creative concepts (lifestyle, flat-lay, bold-color, UGC-style, aspirational) that all obey the shared system.
3. For each, specify where the copy-safe negative space sits so my designer can drop text without recropping.

OUTPUT FORMAT — a table with columns: Concept | Image Prompt (+ aspect ratio) | Copy-Safe Zone | Why It Converts.
End with a NEGATIVE PROMPT line reused across all 5.

CONSTRAINTS: No fabricated claims or fake awards in the image; no copyrighted characters; keep at least 25% of frame low-detail for overlay; match [PLATFORM] aspect ratio; ensure the offer is visually legible at thumbnail size.
