Pacific Moss & Mist (Deep slow-wave / delta)

[start] [Global constraint: natural only; exclude instruments/human voice; prioritize low-variance textures; keep spectral balance warm, non-piercing] [Spatial: very slow L↔R wind sway (~0.05–0.08 Hz); brook mostly centered-wide] [Sleep-stage intent: Deep delta; minimize novelty; emphasize safety and continuity] [0:00–1:30 Intro] [Brook murmur wide-center as constant base; low-pass gently] (Mossy branch micro-creaks, soft and sparse) [1:30–3:30 Ambient Layering] [Wind sighs in long, even breaths; amplitude mod slight] (Rare raven croak mid-distance, <1/min; very low) (Distant woodpecker taps, muffled, infrequent) [3:30–5:30 Minimal Progression] [Reduce event rate further; keep brook steady, slightly louder] (Wind pulses continue with longer cycles) [No sudden changes; sustain deep calm] [5:30–6:30 Outro] [Let all sporadic sounds cease; leave brook + faint wind] [Very long fade to near-silence] [end]
