 All parts use two music systems per page, with a single system only when the score ends on an odd system. Lines break only between measures and share consistent staff/TAB widths. A measure that cannot fit at readable spacing fails with a diagnostic instead of being split. Tall notation is scaled uniformly to fit the two rows; guitar notation and TAB stay together and aligned. TAB displays frets and ties without duplicate rests; standard notation retains the complete rhythm. The generated `.pages/*.png` files are the same page images displayed by the product.
 
-Electric melody prioritizes four-string chords, then melody on top. Every generated guitar chord requires the root, the fifth, or both; neither is preferred over the other. Acoustic favors simple grips, allowing bass plus two upper notes when that is easier than a four-note shape. Defining chord tones remain mandatory. Acoustic and electric chord scoring balances movement and span with a lower-position preference: the highest fret adds one effort point per fret, plus two more per fret above 12. Frets 13-20 remain available when movement savings justify them. Exact melody pitches and rhythms remain unchanged, and unharmonized melody placement retains its existing proximity scoring.

Acoustic favors simple grips, allowing bass plus two upper notes when that is easier than a four-note shape. Defining chord tones remain mandatory. Acoustic and electric chords share a combined effort score for shape difficulty, fret height, and movement, so a compact mid-neck grip can beat a stretched lower one. Shape difficulty adds three points per fret of span and two per additional distinct fret. Height adds one point per fret, plus two more per fret above 12. Acoustic transitions weight per-string movement by two; electric retains its doubled-center movement metric. Frets 13-20 remain available when the overall tradeoff justifies them. Exact melody pitches and rhythms remain unchanged, and unharmonized melody placement retains its existing proximity scoring.
 
 Write all music in reading order: repeat bars, numbered endings, navigation jumps, and pass-specific ties are rejected. The seven-section performance arrangements remain fully written out. Chord labels use `M`, `m`, `aug`, `dim`, `sus`, and `mM7`, including explicit major triads such as `CM`. Recognized Soundslice text-only harmonies are normalized into structured chords; parenthesized chords mark optional turnarounds omitted from the final arrangement ending.
