Outcome: Use or define Aqua to make the visual experience clear and easy to use. User context: A retro media tool uses one glowing blue main button with simple pinstriped panels. Design concept to apply: Aqua. Why it fits: Use it for a planned reference to early desktop software or as one small, touchable-looking accent. Do not use it when: Never copy assets owned by the platform or let glare and low-contrast gloss harm modern accessibility. 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): It is official for that source. Other platforms or teams may use the term in another way. Unknowns to confirm: Brand limits, amount of content, supported themes and languages, target devices, and design-system rules.

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.
