Source knob cycles through 6 tracks: the original CC-licensed Spirals intro plus 5 N-Spheres tracks (Function, Intersect, Attractor, Flux, Core) by Fenderson & Hansi3D. - 48kHz FLAC conversions served via git LFS (~189MB total) - Rotary knob with CSS custom property composable transforms - Dynamic attribution (CC link for Spirals, album credit for N-Spheres) - Signal selection persisted in localStorage - Loading state overlay while buffering larger tracks - Skin-aware labels (465: "Source", 545A: "Input") - Keyboard accessible (Enter/Space to cycle)
