Match the artifact to the decision.
HTML earns its place when spatial, visual, comparative, or interactive expression makes the work easier to understand.
WireframesTest hierarchy, content, navigation, and responsive structure.PrototypesTest a credible flow, its behavior, and its relevant states.DiagramsMake relationships and system behavior easier to inspect.PlansKeep implementation sequences legible and source-grounded.
Use HTML when the thing itself carries the explanation.

See structure
Make layout, hierarchy, and responsive choices visible.
Test behavior
Exercise states, feedback, recovery, and product boundaries.

Give collaborators an artifact they can inspect and direct.
