Page and component responsibilities
The page defines physical dimensions and component placement. Components render static design content or values bound from the template schema.
Choose page dimensions before detailed layout work and verify printed output when physical size matters.
Supported building blocks
Use text for static and dynamic copy, images and SVG for approved visual assets, QR codes for supplied values, shapes for visual structure, tables and repeated groups for arrays, and groups for related elements.
Keep components focused. Complex business decisions should be resolved before the payload reaches the template.
Layout testing
Preview minimum, typical, and maximum content. Test long unbroken values, missing optional fields, large arrays, and every supported page size.
A successful render does not guarantee a correct visual result; include visual review or regression tests before promotion.
