- Change the lighting (golden hour, studio softbox, neon night) to shift the mood.
- Add a specific camera or lens reference (e.g. "shot on 35mm, f/1.8") for a photo feel.
- Lock the aspect ratio to match your platform (9:16 for Reels, 16:9 for YouTube).
- Add or remove a style modifier like "cinematic", "minimalist", or "editorial".
