  "summary": "A transition should not make someone pay a physical price for pressing a button.",
  "kind": "protocol",
  "body": "Offer a way to suppress non-essential motion triggered by interaction, while preserving the information and action. WCAG addresses this in a Level AAA criterion; do not relabel it as a blanket AA rule or a ban on every animation.",
  "limits": [
    "Some animation is essential to explaining movement. Provide appropriate alternatives and avoid claiming that one setting makes all content symptom-free."

      "claim": "WCAG 2.3.3 at Level AAA requires interaction-triggered motion animation to be disableable unless essential to the functionality or information.",

  "use_when": [
    "Navigation or feedback triggers sliding, zooming or other substantial motion."

  "example": "A completed exercise changes status immediately in reduced-motion mode instead of sending the card spinning across the screen.",
  "check": "Can the same task be understood and completed with non-essential motion disabled?",
  "steps": [
    "Identify which motion communicates essential information and which is decoration.",
    "Provide a reduced-motion path or honor a relevant user preference in the implementation.",
    "Test that state changes remain clear when movement is removed."
