Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience.
Outcome: Use or define Enter, Exit & Crossfade to make the visual experience clear and easy to use. User context: In a filtered list, old items fade out before new items settle into place. Design concept to apply: Enter, Exit & Crossfade. Why it fits: Use these patterns to show what changed without making people find their place again. Do not use it when: Never make an exit so slow that the interface feels blocked. Design requirements: Set the content order, shared design values, and reusable components. Define how the layout changes by screen size and state. Keep useful design choices separate from decoration. Inclusion and resilience: Check contrast, zoom, languages, themes, and reduced motion when needed. Do not use color or effects as the only way to show meaning. Acceptance criteria: The design stays clear on phones and desktops, at zoom, in every theme, and in all supported languages. Interactive states stay clear and consistent. Evidence and limits (evidence boundary): No single official standard controls the whole term. Its meaning may change across teams, platforms, or frameworks. Unknowns to confirm: Brand limits, amount of content, supported themes and languages, target devices, and design-system rules.

Review the current use of Enter, Exit & Crossfade. Definition: Enter, exit, and crossfade add, remove, or replace content. They help the change look smooth and connected. Release checks: Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience. Before changing code, report the evidence you found, gaps, severity, and the smallest safe fix.
