Use Case: Tech Pack Translator

Create one polished public-gallery concept image titled exactly "Use Case: Tech Pack Translator".

Use case: productivity-visual / fashion production handoff / technical drawing workflow.
Asset type: portrait A3 fashion tech-pack proof sheet for a GPT Image 2 gallery.

Primary request: Show GPT Image 2 turning a fictional garment brief into a production handoff sheet. The artifact must be a no-people, no-brand technical document, not a product ad, not runway/editorial fashion, not a marketplace listing, not a dashboard, not a menu, not a map, not a comic, and not a 2x3 research board.

Composition: one tall A3 tech pack proof on a muted drafting table. The fictional garment is "Northline Field Overshirt", with no logo and no real brand. Show crisp front and back technical flats in black line art. Below them show exploded paper pattern pieces with labels, grainline arrows, notches, dashed seam allowance lines, pocket pieces, yoke, sleeve, collar, collar stand, cuff, placket, and a 5 cm print scale square. Add construction callouts for topstitch, bar tack, button placement, sleeve placket, hem, and pocket flap. Add a small bill-of-materials zone with generic fabric swatches and trims. Add a right-side reviewer rail with short labels: "FIT", "GRAIN", "NOTCH", "STITCH", "SCALE".

Visual style: production-document clarity, crisp vector-like linework, subtle paper texture, cream paper, thin red review marks, blue construction callouts, graphite typography, practical workshop proofing mood. The document should feel inspectable and useful as a manufacturer-facing handoff preview.

Safety and originality constraints: fictional garment only; no real apparel brand, no logo, no marketplace listing, no celebrity/model/person, no face, no mannequin, no protected costume, no cosplay, no real designer name, no real body measurements, no medical/legal/safety claim, no public figures, no politics/elections/parties, no harmful instructions, no adult/explicit content, no gore, no copyrighted characters, no living-artist style imitation. Do not copy any external prompt, sewing pattern, dataset sample, article image, product UI, source image, artwork, garment design, layout, or protected style.
