Podsumowanie	Card Sorting is a participatory design technique where users organize content items (represented on cards) into logical groups and categories. Used primarily for information architecture design, card sorting reveals how users naturally think about and categorize content, providing empirical data for navigation hierarchies, menu structures, and taxonomy design. The method exists in open form (users create their own categories) and closed form (users organize cards into predefined categories), each revealing different insights about user mental models and organization preferences.	First-Click Testing is a rapid, quantitative method for evaluating whether users click on the correct element to start a task on a web page or screen. Users view a screenshot or live page and are asked to click where they would start a specific task. The test measures success rate (correct first click) and records which elements are commonly misclicked. Unlike tree testing (text-only navigation), first-click testing preserves visual design, isolating navigation labeling and visual information architecture in realistic context.
