Prompt pattern
Keep the page still
Nothing moves except in direct response to something the visitor did.
Fills the motion part of a prompt.
Do not animate anything on load or on scroll. The only movement allowed is immediate feedback to a visitor action, such as a button pressing in or a menu opening. No carousels that advance on their own, no counters that tick up, no floating shapes.
Use this motion pattern when it changes the result the agent should produce. It provides one concrete direction without deciding unrelated parts of the website.
