#!/usr/bin/env bash
# provision-labels.sh — Create/update OCL labels across all active repos.
# Idempotent: safe to re-run. Updates color/description if label exists.
#
# Usage:
#   ./provision-labels.sh                  # all active repos
#   ./provision-labels.sh ocl_issues       # single repo
#   ./provision-labels.sh --dry-run        # preview without changes
#
# Requires: gh CLI (authenticated), yq
