Use Case Vapor: Prompt Condensation Chamber

Create one polished public-gallery concept image titled "Use Case Vapor: Prompt Condensation Chamber". Output format: a single 2:1 panoramic macro product photograph of a fictional tabletop condensation chamber: a shallow black acrylic oval with safe cool mist, illuminated dew trails, chilled glass vanes, dew-writing strips, memory plume rings, soft eraser paddles, frame frost arcs, coherence beads, and a clear holding bell. The invented subject is a pearlescent violet comma comet with two brass fins and one mint dot, repeated exactly inside the final bell. Mechanism labels: Kernel Puff, Scene Humidity, Memory Plume, Steer Vane, Erase Chill, Word Dew, Frame Frost, Coherence Bell, Trace Hold. Show prompt control as condensation behavior: humidity changes context, plume rings preserve memory, vanes steer instructions, eraser paddles remove stray curls, dew-writing tests short text, frost arcs change framing, beads test consistency, and the bell holds the same subject. No people, no hands, no logos, no real lab equipment, no real radiation, no dangerous procedure. Premium tactile studio photography, black acrylic, cool mist, pearlescent violet, mint accent, clear glass, brass hardware, crisp readable tiny labels; fictional, original, unbranded, harmless, rights-safe.
