/**
 * ESLint configuration file for the project.
 *
 * This configuration sets the environment to support browser, Node.js, and ES2021 features.
 * It uses the latest ECMAScript version and module source type.
 * The configuration extends the recommended ESLint rules and enforces the following custom rules:
 * - 2-space indentation
 * - Mandatory semicolons
 * - Single quotes for strings
 * - Trailing commas in multiline constructs
 * - No space before function parentheses
