/**
 * grade_skin_tones — file-only skin-tone match across clips. Derives a
 * vision-tuned grade from REFERENCE vs TARGET frames and bakes it into a
 * graded output via ffmpeg (colorbalance + selectivecolor + eq). Works on
 * every host (no NLE required); the agent can then `replace_clip` the
 * graded file onto the timeline.
 *
 * NOT a deterministic match (no ColorChecker). Use when "shots feel off"
 * (different camera, location, white balance drift). Below confidence 0.4
 * the grade is unreliable — surface the result and let the user grade
 * manually.
