Speed up to 88 BPM and vary the reprise

Tempo 70 -> 88: slowed, but with an actual pulse.

• BASS2 — busier eighth-note walking bass

• MEL2 — higher, more ornamented lead variation

• DRUMS2 — ghost snares + open hats on the offbeats

• FILL macro: a 2-beat snare-roll into each drop (into the full kit at the end of cyc C, and out of the interlude into the reprise).
