#!/usr/bin/env bash
# Install WordPress core + test suite for running PHPUnit locally or in CI.
#
# Usage: install-wp-tests.sh <db-name> <db-user> <db-pass> [db-host] [wp-version] [skip-database-creation]
#
# Sourced from the standard WP-CLI scaffold script, lightly hardened:
#   - set -euo pipefail
#   - quieter curl
#   - supports WP_TESTS_DIR / WP_CORE_DIR overrides via env
#
# Why vendored: the script is stable, changes rarely, and vendoring avoids a
# curl-from-github step in CI. Kept here so the CI workflow is reproducible.
