Sentient Weed's Harbinger Sound

A sensory phenomenon—an eerie, rhythmic sound that serves as a narrative harbinger of the sentient weed's sentience and proximity. Unlike the physical colony, this sound is ephemeral, auditory, and symbolic, designed to escalate tension and confirm the weed's infiltration into the refinery. It is not a physical entity but a warning sign tied to specific moments (e.g., Victoria's detection in the Pipeline Room, the shattering of an emotional moment between Jamie and Victoria).
