Tell us what you're making.
What this is. The customer never gets a blank canvas: the occasion curates the cabinet, and every control is a choice among things the studio can defend and fulfill — Library palettes, the CultureSchool archive of prints and works, house ornament, house typography in fixed positions. There is no upload, no colour picker and no font menu, and the ground, border, centre and mark are each chosen from a closed set. The preview is the same deterministic composition the production file uses, so what you approve is what gets made. Previews carry the archive watermark — the clean originals are held back and printed from directly. Every piece ships with a provenance card naming the palette, its origin and its credit.
