/**
 * - High Obfuscation preset.
 * - **Average 90% performance reduction.**
 *
 * ## **`Enabled features`**
 * 1. Variable renaming
 * 2. Control flow obfuscation
 * 3. String concealing
 * 4. Opaque predicates
 * 5. Dead code
 * 6. Dispatcher
 * 7. Moved declarations
 * 8. Object extraction
 * 9. Global concealing
 * 10. Minified output
 *
 * ## **`Disabled features`**
 * - `eval` Use at your own risk!
 *
 * ### Potential Issues
 * 1. *String Encoding* can corrupt files. Disable `stringEncoding` manually if this happens.
 * 2. *Dead Code* can bloat file size. Reduce or disable `deadCode`.
