Runway 靜態圖 → 動態轉場

Runway Gen-4 image-to-video workflow:

**Start frame**: {{start_image}}
**End frame**: {{end_image}}
**Transition style**: {{transition_style}}
**Duration**: 5 seconds

Gen-4 generates the intermediate frames. The transition should be:
- Smooth (no jarring cuts)
- Style-preserving (color palette + texture continuity)
- Reasonable motion physics (objects don't teleport)

Lighting and color grading should blend across the transition. Final frame matches the uploaded end image exactly.

Use cases this is good for:
- Comic / storybook page transitions
- Before/after product comparison
- Seasonal / time-of-day shift
- Brand identity reveal (logo construction)
- Style transformation showcase

Notes:
- Both images should have similar composition / framing for best results
- Wildly different images will produce surreal interpolation (sometimes desired!)
- 5 seconds is sweet spot — longer can feel slow, shorter feels rushed
