/* Ornament Crop — v2
 *
 * Aesthetic: cream paper (#F8F5EE), dark ink. One serif + one mono.
 * No UI chrome beyond a crop frame, three frame-size buttons, an optional
 * caption input on the artifact screen, and the action buttons after lock-in.
 *
 * v2 changes vs v1:
 *   - Caption input on artifact screen (max 40, mono, single-line).
 *   - Archive link in the footer (text only, no logo).
 *   - Archive placeholder page styling.
