- nullnoise.c grows a 'noisetype' score keyword — each parallel group carves from its own material: brown (leaky-integrated, dark lows), white (raw LCG, crisp tops), velvet (sparse impulses, hiss-free sustain), pink default. RMS-matched so peakDb reads the same across groups; flat chain still proofs to bit-exact silence for every type. - cutezenith: the layered cutezen-lane peak — 160 bpm, 96 bars, exactly 2:24, C pentatonic; pink sings / brown holds the lows / velvet pads / white tops, short naked-hook intro, still-section hush, pent-ladder counter-line in the finale.
