## Architecture (v7.0+)

The plugin uses a modular class-based architecture:

- **`classes/FileHandler.php`** - Atomic file operations with locking to prevent data corruption
- **`classes/EventCache.php`** - Caching layer with 5-minute TTL for improved performance
- **`classes/RateLimiter.php`** - AJAX rate limiting for security (60 req/min read, 30 req/min write)
- **`classes/EventManager.php`** - Consolidated event CRUD operations

## Requirements

- DokuWiki (Hogfather or later recommended)
- PHP 7.4+
- Modern browser (Chrome, Firefox, Edge, Safari)
