Prompt pattern
Reference an era with a few deliberate cues
Limited period-inspired type, colour, and imagery can feel nostalgic without becoming costume-like.
Fills the style part of a prompt.
Choose one reference period, then use 2 or 3 matching cues such as a muted palette, period-style type, or grainy photography. Keep modern navigation, readable text, and current accessibility expectations beneath the visual treatment. Do not combine unrelated decades or make the interface harder to use for the sake of nostalgia.
Use this style pattern when it changes the result the agent should produce. It provides one concrete direction without deciding unrelated parts of the website.
