# lib/logger.sh — Shared logging library

# Usage from any script:
|

# source "$(dirname "$0")/lib/logger.sh" "operation-name"
|

#
|

# The first argument becomes the log file prefix.

|
# Example: source lib/logger.sh "deploy" → logs/deploy-20260512-123456.log

# Override log level at runtime:
|
|
# export LOG_LEVEL=DEBUG
