Marquetry Grain Contrast Readback

Use [marquetry reference], [wood palette] and [panel dimensions]. Produce a 50-second gallery description explaining how changing grain direction separates the supplied shapes. Name species only when documented and distinguish visual interpretation from construction evidence.

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.
