Notes

• Accepts two file fields: file (required, the main screenshot) and backgroundImage (optional, used when backgroundType is image).
• Supports HEIC, RAW, PSD, and SVG input formats (automatically decoded).
• Shadow presets map to specific values:
  • subtle: blur 20, offsetY 4, opacity 20%
  • medium: blur 40, offsetY 10, opacity 35%
  • dramatic: blur 80, offsetY 20, opacity 50%
• Social media presets resize the final output to fit the target dimensions using contain mode:
  • twitter: 1600x900
  • linkedin: 1200x627
  • instagram-square: 1080x1080
  • instagram-story: 1080x1920
  • facebook: 1200x630
  • producthunt: 1270x760
• Device frames (iphone, macbook, ipad) apply a hardware bezel around the image and skip the borderRadius setting.
• When transparency is required (shadow, border radius, device frames, or transparent background), the output is forced to PNG even if jpeg is selected.
• Image backgrounds are not supported in pipeline/batch mode.
