Sketches genuinely different layout hypotheses as ASCII wireframes before any hi-fi design work starts - three by default, or the number the user names, anywhere from 2 to 5. Use when a user asks to "show me some layout options", "sketch a few wireframes", "give me 3 versions of this screen", "draw two layout directions for this page", "explore layouts before Figma", or "ascii wireframe this". Do not use for pixel-faithful HTML mockups built from a reference screenshot - use html-mockup for that.
