Distinct from flyer-maker:
- Smaller aspect ratios (mostly horizontal, often extreme like 728×90 or 1456×180)
- Dense text + CTA conventions (ad copy, not editorial)
- Per-preset standard sizes (no custom aspects in v1)
- "Ad feel" aesthetic — direct, conversion-focused, brand-loud
Distinct from cover-maker / thumbnail-maker:
- No artist / author / title-as-subject
- Standard ad-platform sizes (presets, not "medium")
- Includes explicit CTA element
- Very small visual zones in some presets (300×250 has ~80% text)
