Prompt pattern
Frame a section with quiet abstract shapes
A few large forms around the edges add character while leaving the message unobstructed.
Fills the background part of a prompt.
Place 2 or 3 large abstract forms at the outer edges of a section, with no more than 10 percent opacity where text sits above them. Use one shape family and two related colours so they feel intentional. Do not place shapes behind small text, buttons, or form fields, and do not let them drift around the page.
Use this background pattern when it changes the result the agent should produce. It provides one concrete direction without deciding unrelated parts of the website.
