Interface refinement begins after the basic structure works. Designers and builders inspect hierarchy, spacing, component states, motion, responsive behavior, content fit, accessibility, and consistency with the product's visual identity.
Each revision should address observed evidence rather than add random decoration. Focused passes make it easier to preserve working behavior while turning a generic draft into a coherent and intentional application.

Interface refinement is the process of improving a working screen until it feels clear, coherent, and suited to the product. It treats the first generated draft as material to examine rather than a finished design.
For example, a builder can first correct spacing, then add missing hover and focus states, then adjust animation and brand details. Each pass has a specific goal that can be reviewed without rebuilding everything.
