User Preference Respect

The operating system already knows what the user needs. Your job is to listen and respond. These preferences exist because people set them deliberately — ignoring them overrides the user's own accessibility decision.

The Preferences

prefers-reduced-motion

What it means: user experiences discomfort or harm from motion. What to do:

• Disable all decorative animation
• Replace slide/fade transitions with instant state changes
• Keep essential motion (loading spinners) but simplify
• Disable parallax, scroll-triggered animation, and auto-advance
• Never override this preference
