Six factual corrections: slash chord definition (inversions vs on-chords),
logits described as unnormalized, #11 = eleventh not fourth, duplicate
Polukadentsiya sentence removed, pre-training LR corrected to 1e-4,
unverified PAD index claim removed. All ML term explanations rewritten
with analogies accessible to a near-beginner.
