6 * Logging configuration
7 * This project uses two logging systems:
8 * 1. Console logging (development/client-side) - controlled by console stripping
9 * 2. Pino logging (server-side) - controlled by LOG_LEVEL
10 * 
11 * LOG_LEVEL affects both systems:
12 * - error: only error logs
13 * - warn: warn and error logs
14 * - info: info, warn, and error logs (default in production)
15 * - debug: all logs (default in development)
