v6 — Does SA3 recognise named electronic-music artists?
36 artists × 3 prompt modes × 2 seeds. For each artist, compare the three modes back-to-back: does just naming the artist land their sound, or does the descriptor route (the one we know works) get closer?
bare — just the name
context — "in the style of X, genre, BPM"
descriptor — signature sound, no name (control)
