Design intent
Design intent is the product decision and intended behaviour that an implementation must preserve across content, state, devices and constraints.
What design intent means
Design intent includes information priority, interaction, feedback, consequence, responsive change and accessibility.
Pixel identity can conflict with intent when content or viewport changes. A desktop comparison table may become labelled mobile records because reading order and action priority matter more than preserving columns.
Design to code translates this intent into software. Implementation QA checks the running behaviour, while a Design-to-Code Audit can diagnose wider correspondence failures.
