Prompt pattern
Give a flat surface a little printed character
Very light grain can make a page feel tactile without making it look aged or dirty.
Fills the background part of a prompt.
Apply a fine paper or grain texture at no more than 5 percent opacity over a plain base colour. Keep the texture uniform behind the whole section and use flat panels where forms or dense text need extra clarity. Do not use a photographed texture with visible stains, folds, or words.
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.
