+ * audit-hardcoded-colors.js
+ *
+ * Scans GDevelop UI source files for hardcoded hex color values that should
+ * instead use a design system token from the theme variables.
+ *
+ * Usage:
+ *   node scripts/audit-hardcoded-colors.js
+ *   node scripts/audit-hardcoded-colors.js --path src/UI
+ *
+ * Exits with code 1 if violations are found (CI-ready).
