Storybook and Visual Regression Gate

Purpose

Make reusable component quality reviewable and prevent accidental visual drift without treating screenshots as semantic or interaction proof.

When to Use

• Reusable components change across variants, states, themes, densities, or responsive containers.
• CSS or dependency changes can affect rendered output.

Do

• Cover default, variants, critical states, content extremes, themes, and responsive containers with deterministic dates, data, fonts, network, and animation.
• Add interaction and accessibility checks alongside screenshot baselines.
• Classify diffs as intended, regression, environment noise, or baseline debt and require owned rationale for intended changes.
