Usage:
  ./scripts/workflow_sequential_gates.sh [options]

Options:
  --with-live-shadow   Also run the live still-smoke harness in shadow mode.
  --with-golden        Also run the live golden suite after the other gates.
  --with-cad-parity    Also verify live CAD scene-manifest/model part-key parity.
  -h, --help           Show this help.

Behavior:
  Runs the current minimum workflow verification gates sequentially to avoid
  RAM spikes from parallel test execution.
