Light Without Source（Humming Version）
Instrumental-focused with very soft female humming only (no lyrics, no words), 72 BPM, deep-space ambient minimalism with subtle beauty, transparent high-frequency pads, slow evolving harmonies, extremely restrained humming blended into atmosphere, no vibrato, no lead melody, no piano, no guitar, no build, no drop, serene and distant, light without visible source, gradual disappearance
[Instrumental] (No Vocal)
