- design-stylescbrock84/headcountApplies a deliberate visual direction to an interface — minimalist editorial, industrial utilitarian, or high-polish commercial — each with its own type scale, palette behavior, surface treatment, and motion. Use this when a product needs a point of view rather than defaults, when choosing between visual directions, when an interface reads as generic, or when restyling something without changing its structure.DesignNo warnings★ 2.6K↓ —

- puaLeoYeAI/agent-master-skillsForces exhaustive problem-solving with corporate PUA rhetoric.
