/**
 * Dev-only PROBE 5: decisive test of THREAT-MARKER rendering.
 * Moves pirates ON-SCREEN, enables the (data-disabled) threat layer, lets the
 * NATURAL scene render draw it (no manual update), then freezes and samples
 * pixels at worldToScreen(pirate.x, pirate.y-36). Also sanity-checks that the
 * pirate body itself is visible, and that a neutral's slot stays clean.
