+# ----------------------------------------------------------------------------
+# Purpose:
+# - Provide a consistent, reusable file discovery primitive for repo scripts.
+# - Support multiple glob patterns.
+# - Apply standard ignore rules to reduce noise (vendor, node_modules, .git).
+# - Output one path per line, relative to repo root.
+#
+# Usage:
+#   ./scripts/lib/find_files.sh <glob> [<glob> ...]
+#
+# Examples:
+#   ./scripts/lib/find_files.sh "*.yml" "*.yaml"
+#   ./scripts/lib/find_files.sh "src/**/*.php" "tests/**/*.php"
+# ----------------------------------------------------------------------------
