"🔧📚" represents the perfect combination of practicality and knowledge. It symbolizes modules, which are self-contained units that provide specific functionality or information. These modules can be tools (represented by the wrench emoji "🔧") that help solve problems or accomplish tasks, and they can also be educational resources (represented by the book emoji "📚") that offer valuable insights and learning opportunities. Together, they represent the power of modular systems in enhancing both practical skills and intellectual growth.
