/**
 * clip-decision-cli.ts — B1 standalone proof of the per-beat clip-decision record.
 *
 * Builds a real {@link PerformanceRig} for a synthetic full-humanoid skeleton from the shared
 * standard library and samples a beat, emitting the {@link ClipDecision} so a unit test can assert
 * the B1 contract fields are present and populated:
 *   { intent, clipId, source, bonesTouched, maxRotAmplitudeRad, maxTransAmplitude, reachedGLBRuntime }
 * plus bodyBoneRotationRad + rootTranslation.
 *
 * Browser/GPU/Playwright-free: it drives `animation-performance.ts` directly (the same module
 * scene-player.ts uses), so the proof is of the REAL decision producer, not a re-implementation.
 *
 * Usage: tsx scripts/clip-decision-cli.ts --intent talk --t 0.6
