• GPU Canvas: a WGSL shader decides what you are allowed to see (torch cone, fog inside the beam, grain, flare bloom, the possessed-screen glitch). The relic portal and the mirror are drawn by the Luau script every frame: rings of round-tipped tentacles built from smooth curves that turn in opposite directions, a void core, a blue haze and thin electric bolts; around the mirror, an irregular spectral glow that pulses and smoke that drifts across the girl's face.
