/**
 * PrismBeamHero — a glass prism on black, a white beam going in where your
 * pointer points, and a spectrum coming out the other side.
 *
 * The prism is real geometry: a triangular prism raymarched in a fragment
 * shader, turning once every fifty seconds, with Fresnel reflection and a
 * per-channel refraction of its environment so its faces catch the beam in
 * colour fringes. The light is drawn in screen space over it — a hard white
 * beam with a soft halo, a lens flare where it enters, a fan of spectrum where
 * it leaves, bent toward the base the way a prism bends light. Stars drift
 * behind. Everything is additive light on OLED black, tone-mapped at the end.
 *
 * THE POINTER HOLDS THE LIGHT. Move across the hero and the beam swings to
 * come from where you are; the spectrum sweeps with it. Idle, the beam drifts
