Create one polished public-gallery concept image titled "Use Case Fossil: Prompt Excavation Block". Output format: a single vertical 4:5 museum-prep macro photograph, not a grid, not cards, not a poster, not a board game, not a sand tray, not ice cores, not a library cabinet, not textile fitting, not optical bench, not toy latch, not courtroom, not elevator, not music box, not flipbook, not chessboard, not joinery, not neon tubes, not planetarium, not patchbay, not proof press, not loom.

Scene: a fictional tabletop paleontology prep drawer holds one rectangular stratified plaster excavation block in a shallow walnut frame. The block contains a harmless invented fossil silhouette called a "leaf-sprocket", visible in three small prepared windows. Around it are soft brushes, tracing vellum, foam calipers, colored layer pins, cast molds, and source-safe specimen tags. No people and no hands.

Mechanism: GPT Image 2 prompt design is expressed as careful excavation instead of layout panels. Show these readable labels as small engraved tags attached to physical tools and windows: Matrix Seed, Layer Context, Rubbing Reference, Brush Reveal, Void Mask, Label Pin, Scale Caliper, Cast Proof, Source Crate. The seed subject is embedded in the matrix; context is shown by colored sediment bands; reference influence is a vellum rubbing beside the block; local edits are one brushed reveal window; exclusions are clean empty void masks; text rendering is tested by tiny specimen label pins; aspect and scale are checked with foam calipers; consistency is judged by three cast proof plaques preserving the same fictional leaf-sprocket.

Visual language: premium museum conservation photography, warm walnut, chalky plaster, ochre and slate sediment bands, teal pins, graphite labels, translucent vellum rubbings, crisp shallow shadows, highly readable short labels. Everything is fictional, unbranded, rights-safe, non-political, non-adult, non-graphic, and harmless. Exclude real marks, public figures, restricted characters, imitation of living artists, unsafe instructions, weapons, explicit material, graphic harm, and watermarks.
