Scratchboard Light Recovery Audio

Using [black scratchboard reference], [subject silhouette] and [light direction], deliver a 40-second gallery description of how sparse marks imply light and volume. Design a scratchboard-inspired illustration by exposing pale marks within a dark ground. Preserve deliberate untouched black regions; do not simulate the piece as white paper with shaded pencil strokes. Supply a transcript and timing cues alongside the audio. Keep sound effects below speech, or use no speech when the task calls for an instrumental cue.

Use only the supplied facts and approved wording. If a necessary script or timing reference is missing, ask for it first. Produce the audio when supported; otherwise return the complete spoken script with pauses and a short production cue sheet, clearly labeled as a script. Use original voices and keep speech intelligible without music. Never claim an audio file exists unless it was generated.
