[Instrumental Break] (a dense drone — pure weight, no melody; industrial hiss enters and stays) [Build-Up] (brass surfaces buried beneath; low strings add compression; everything pressing downward) [Interlude] (nothing develops upward; every instrument stays low, a lid on the sound; the hiss thickens; brass recedes further) [Outro] (nothing breathes, nothing opens — the smog line as sound, impassable; it holds and does not release)
