A 4-second ominous logo reveal centred on low D. On frame 0 a dull low knock opens a mono sub rumble on D1 that slowly swells, while a metallic scrape (stick-slip friction exciting an inharmonic resonator bank, sliding across the stereo field) grinds and squeals above it, with a second, harder scrape taking over at 1.0 s. From 1.05 s a reverse cymbal pulls the air in, rising to a sharp stop 45 ms before the hit and leaving a short vacuum. On frame 75 (2.5 s) a massive low brass-like braam lands: a D minor stack (D1 D2 A2 D3 F3 A3) of detuned band-limited saws whose resonant low-pass snaps open and slowly closes, with a pitch bend up into the note, a sub knock and a short crack on the attack. A long, dark hall tail then rolls the braam down to silence. Only the sub, the knocks and the braam's low partials sit below 120 Hz, and they are mono.

- Frame 75: reveal hit
Stems: mono D1 sub rumble + low knock on frame 0, stick-slip metal scrapes through an inharmonic resonator bank (two passes, panned sweeps), reverse cymbal into a 45 ms vacuum (intro hall ducked out), then an additive band-limited braam (D minor stack, 3 detuned saws per note, analytic resonant LP swell, pitch scoop) with sub knock + crack on frame 75 and a 3 s dark hall tail. Side high-passed at 250 Hz (8th order); 60 ms-release true-peak limiter; no flags.
