# Common path definitions for scripts-repo
# Source this file in other scripts for consistent path handling
#
# Usage:
#   source "$(dirname "$0")/paths.sh"
#   # or
#   SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
#   source "$SCRIPT_DIR/paths.sh"
#
# Note: Git hooks (pre-commit, etc.) are copied to .git/hooks/ and cannot
# source this file. They must use their own path detection via REPO_ROOT.
