- The top edge exposes image replacement and cropping.
- Layout
- A narrow left settings column controls a large presentation preview.
- Density
- Dense settings are grouped under clear section headings.
- Color
- Deep purple workspace with green active controls and a multicolor sample background.
- Type
- Small sans-serif labels keep tools and content visually separate.
- Pattern
- Group frame, background, and output-size settings beside a persistent screenshot preview.
- States
- This capture records the visible state only. Loading, error, and later workflow states were not verified.
- Don't
- Adapt the interface pattern with original content, branding, and data; do not infer behavior from a still image.
