Makes Claude thoughtful about visual weight instead of making everything the same size and yelling for attention. It'll push you to use the full toolkit: size ratios of at least 1.5x, whitespace as a signal, color for CTAs, and positioning based on scanning patterns. Includes the squint test, which is genuinely useful for catching when your hierarchy is mud. The four-level system (primary through quaternary) gives you a vocabulary for talking about importance without bikeshedding. Best for when you're building interfaces and need Claude to care about what users see first, not just what looks clean in Figma.
