Use Case Toy Latch: Prompt Key Fitting

Create a single polished public-gallery image titled "Use Case Toy Latch: Prompt Key Fitting". Show one oversized transparent toy diary-latch mechanism on a clean studio workbench, clearly fictional and harmless, not a real security lock, not lockpicking, no tools for bypassing locks. The GPT Image 2 prompt is translated into a chunky colorful key-fitting instrument: Seed Tooth, Context Ward, Reference Pin, Negative Gate, Crop Keyway, Caption Bow, Style Finish, Revision Click, and Turn Proof. The same invented object, a tiny blue paper lantern, appears as an engraving on the key bow, a safe sticker inside the latch, and a final proof window after the toy latch turns. Output format: premium macro product photograph of one transparent acrylic latch and one oversized plastic key with modular tooth blocks, readable labels, soft daylight, no people, no hands, no brand marks, no logos, no public figures, no copyrighted characters, no political content, no harmful instructions, no weapons, no gore, no sexual or nude content, no living artist style imitation. Avoid contact sheets, 2x3 boards, cards, grids, research posters, optical benches, library cabinets, textiles, chessboards, elevators, marionettes, neon tubes, sand trays, terrariums, mosaics, music boxes, and courtroom scenes.
