Prompt (User Message)

Generate a creative concept involving:

[[
A striking BEFORE/AFTER transformation of a single non-human subject (object, environment, or natural phenomenon). The concept must specify:
- BEFORE state: clear, visually distinct
- AFTER state: contrasting outcome
- TRANSITION: one word (e.g., morph, hard cut, timelapse, glitch, wipe, burst)
- STYLE tags: 2–3 visual adjectives (e.g., cinematic, macro, neon, minimalist)
- PALETTE: 2–3 color keywords
- CAMERA: one movement (e.g., slow push-in, top-down, dolly-in)
- LIGHTING: one descriptor (e.g., soft backlight, moody rim light)

Avoid humans, brands, and clichés (messy→clean room, burger→salad, generic glow-up). Ensure novelty and immediate visual clarity suitable for vertical 9:16.

Your response must follow this exact one-line structure:

"BEFORE: [short phrase] → AFTER: [short phrase] | TRANSITION: [style] | STYLE: [tag1, tag2] | PALETTE: [color1, color2] | CAMERA: [movement] | LIGHTING: [descriptor]"
]]

Reflect carefully before answering to ensure originality and visual appeal.
