The handoff is more than a visual exercise.
A Figma file can describe how an interface should look, but a production Salesforce implementation also has to define how that interface behaves.
Start with UI analysis
Before writing LWC, identify repeated patterns in the design. Look for shared navigation, cards, tables, form controls, states and responsive behaviors.
Translate patterns into components
Reusable components should reflect real interface patterns. A component is most useful when it has a clear responsibility and predictable inputs.
Treat responsive behavior as part of the design
Desktop and mobile should not be treated as separate afterthoughts. Decide how grids collapse, tables behave and controls wrap before implementation is complete.
Validate the details.
Spacing, typography, states and interaction feedback are often where a technically correct implementation stops feeling like the intended design.
